PT 110 Lesson 10: Using Advanced Mixing Techniques Review and Discussion Questions

  1. How is the Do-To-Selected function useful? What keyboard modifier set is used to access Do-To-Selected functionality? To apply the same action to multiple tracks. opt-shift
  2. Describe the process of creating a drum submix. What kind of track is traditionally used as a submix destination? 1. TRACK > NEW Aux 2. Set output for all tracks that you want included in the submix to the same available mix bus using AUDIO OUTPUT PATH SELECTOR (opt-shift to do this to all of them at the same time) 3. Set the Input for the Auxiliary Input track to correspond to the internal Mix Bus chosen in step 2 using the AUDIO INPUT PATH SELECTOR. 4. Set the output of the auxiliary input track to your main stereo output using the AUDIO OUTPUT PATH SELECTOR. 5. Solo-safe the Auxiliary input track (cmd+click Solo button). An Aux track is usually used as a submix destination.
  3. What is the difference between a Basic Folder track and a Routing Folder track? Which kind is useful for sub mixing? A Basic Folder track is nothing more than a holding container for other tracks. If you do not need submixing, group processing and routing control, but you would like to collect tracks together for organisational purposes, use one of these. Although Basic Folder tracks provide MUTE and SOLO controls, constituent track signals do not pass through the Basic Folder track in anyway. Routing folders have the added advantage of being able to submix constituent tracks, routing audio similar to an Aux.
  4. What processes can you use to route the outputs of a set of tracks to a destination track ? 1. Route Tracks to New Folder checkbox in right-click menu) 2. Using AUDIO OUTPUT / INPUT SELECTORs (as Q2 above) with Routing to Buses or Routing to Tracks submenus.
  5. What is the purpose of grouping tracks? How many track groups can you create in a session? To organise and control a set of tracks by linking tracks and their controls104: in four banks of 26 Group IDs (a-z)
  6. What are some of the parameters that are affected by Edit groups? What are some of the parameters that can be included in a Mix group? Edit Groups: Track Views, Track Heights, Track Timebase, Elastic Audio assignments, Audio and MIDI editing functions, Playlist views, Selection based processing (i.e AudioSuite and Consolidate), Automation Editing. Mix Groups: Track Volume, Track Pan, Automation Mode Settings, Track Mute, Track Solo, Record Enable, Send Levels, Send Panning, Send Mute, Insert Controls (plug-in parameters)
  7. What is the keyboard shortcut to create a Mix or Edit group from selected tracks? cmd+G
  8. How can you enable or disable a track group? How can you globally suspend all groups? How can you visually tell when groups have been suspended? 1. GROUP LIST – click Group to toggle 2. GROUP LIST POP-UP > SUSPEND ALL GROUPS (or cmd+shift+G) 3. The Group list will be dimmed.
  9. How can you identify group membership of tracks in the Mix window? GROUP ID INDICATOR and its TRACKS pop-up menu.
  10. How can you quickly select all members of a group? How might this be useful? 1. Groups List: click column to the left of a group name. 2. GROUP ID INDICATOR > TRACKS pop-up menu > Select Tracks in Group.
  11. What are some options for modifying or deleting a group? Modify: 1. GROUP LIST POP-UP MENU > MODIFY GROUPS 2. MIX window: GROUP ID INDICATOR > MODIFY 3. Right-click group name in Group List > MODIFY Delete: 1. GROUP LIST POP-UP MENU > Delete Active Groups 2. MIX window: GROUP ID INDICATOR > DELETE 3. Right-click group name in Group List > DELETE
  12. What is the purpose of the ALL group? Can you modify track membership or delete this group? To apply global changes. Membership in the ALL group cannot be modified, nor can the group be deleted.
  13. When is it necessary to apply dither? Where should you insert a dither plug-in? When you are down-sampling, e.g a bounce down to 16-bit distribution ready .wav from a 24 bit/32 bit floating-point session. Insert on Master Fader.
  14. What is noise shaping used for in a plug-in? How is noise shaping used by the POW-r dither plug-in? Noise shaping helps improve the signal to noise ratio of dither. The process exploits the Fletcher-Munson loudness contour, which graphs the sensitivity of the human ear (in dB) across the frequency spectrum. POW-r noise shaping improves audio performance and reduces the perceptible noise inherent in dither by shifting noise components into a less audible range. (POW-r = Psychoacoustically Optimised Word-length reduction). Type 1: For solo instrument recordings, spoken-word i.e material with less stereophonically complex material with a narrow dynamic range. Type 2: for moderate stereophonic complexity (rock, pop). Type 3: Especially suited to material with a broad dynamic range. Designed for full spectrum, wide stereo field material (classical, orchestral)
  15. What are the steps involved in creating a session archive? Why is it important to use to the Save Copy In command for compacting sound files? 1. Clear unused clips from the session without permanently deleting any audio (See Lesson 7): CLIP LIST POP-UP MENU > SELECT UNUSED > CLEAR > REMOVE 2. Create Session Copy: FILE > SAVE COPY IN (this insures that all files needed for the archive are copied into the corresponding Audio Files and Video Files folders. This will also protect the original files against accidental data loss.) 3. Compacting sound files.CLIP LIST POP-UP MENU > SELECT ALL > COMPACT

PT 110 Lesson 9: Writing and Editing Automation Review and Discussion Questions

  1. What are some of the parameters that you can automate in ProTools? 1. Track Controls (Volume, Pan, Mute for Audio, MIDI, Instrument and Aux and Master Fader volumes. 2. Send Controls (Send Volume, Send Pan, Pan Mute) 3. All plug-in controls
  2. What are some of the differences between MIDI continuous control data and ProTools audio automation? What kind of tracks can ProTools audio automation be used on? MIDI: CC automation data is stored within the associated MIDI clip. Audio: although an audio track can have multiple alternate playlists (See Lesson three) an Audio track’s single automation playlist applies to all playlists on a track. Audio automation is used for Audio and Auxiliary track – it offers significantly higher resolution than MIDI CC automation.
  3. What selector can you use to set the automation mode for a track? Where is this selector located? Automation mode selector available in both the Mix and Edit windows.
  4. What is the difference between the Write, Touch, and Latch automation modes? 1. Write: Automation starts writing for all enable parameters when playback starts, overwriting any previous automation data. Writing stops for all parameters when playback stops2. Touch: Automation starts writing when an enabled parameter is being modified. Modified parameters only write automation while being held. Writing stops when modified parameters are released – the parameter returns to the previously automated value. 3. Latch: Automation starts writing when an enabled parameter is being modified. Modified parameters continue writing after being released. Writing stops for all modified parameters when playback stops.
  5. When might you suspend automation? What is the difference between the Suspend button and the Write Enable buttons? To obtain hands on control of parameters for an unfamiliar sessionSuspend: Suspends all writing and playing of automation for all tracks. Write Enable: Toggles writing of corresponding automation across session, has no effect on automation playbackWINDOW > AUTOMATION, cmd+4 (alphanumeric)
  6. What are the advantages of using Touch or Latch mode over using Write mode? In what scenarios would you use Latch mode? When would it make more sense to use Touch mode instead? Both Touch and Latch only write automation to parameters that are changed allowing you to be more selective. Latch: to set a parameter over long sections of a mix – perhaps useful for an initial automation pass. Touch: to touch up small sections of existing automation
  7. What are two ways to display an automation playlist in the Edit window? 1. TRACK VIEW SELECTOR 2. SHOW / HIDE LANES
  8. What are some common automation graphs that you may work with? How might automation graphs be different for different types of parameters, with respect to the available vertical positions? Audio (top to bottom): Volume graph (-INF to +12db) Mute graph (Mute / Not Muted), Pan (<100 to 100>), Send (Level, Mute, Pan) MIDI (0-127) (top to bottom): Velocity, MIDI Volume, MIDI Mute. MIDI Pan, Pitch bend, Aftertouch, Program change, SysEx, Controllers.
  9. What are some ways that the Grabber tool can be used to edit an automation playlist? How would you go about nudging automation break points? Click to create a break point. Drag up or down change the dB value, drag left or right adjust timing. opt-click: delete breakpoint. Select breakpoint(s) > choose nudge increment from the NUDGE VALUE POP-UP MENU in the Edit window toolbar: +/-alphanumeric
  10. What are some ways of the Pencil tool can be used to edit an automation playlist? Freehand, Line, Triangle, Square, Random (not Parabolic or S-curve)
  11. How is cutting automation data different from deleting automation data? Cut adds break points at the start and end of a selection, while the delete key will not
  12. What will be the result if you copy automation (Edit > Copy) from a track displaying Volume automation and paste it (Edit > Paste) on a track displaying Pan automation? Automation data pasted to the same automation graph that it originated from, even if the corresponding automation graph is not currently displayed on the target track.
  13. How would you go about duplicating the volume automation for a track onto Send B for the track? PASTE SPECIAL MODE
  14. How can you delete individual breakpoints in an automation graph? How can you delete a range of automation break points? 1. Grabber opt-click. 2. Select range >Delete
  15. How can you clear all automation on a displayed automation graph? What modifier can you use to clear all automation for a track? Triple click on the automation graph (or cmd+A (Select All) > Delete (ctrl+Delete to delete ALL automation on all automation playlists on the track(s) in the selected range). To clear automation from multiple tracks extend the selection across all of the target tracks. In such a case be sure that each track is displaying an automation graph

PT 110 Lesson 8: Basic Mixing and Signal Flow Review and Discussion Questions

  1. Where can you assign the colour coding that Pro Tools will automatically apply for tracks and clips? How can you display track colour bars in the Mix and Edit windows? SETUP > PREFERENCES> DISPLAY > Color CodingVIEW > MIX WINDOW VIEWS / EDIT WINDOW VIEWS >TRACK COLOUR or Mix / Edit Display Selector
  2. Describe the track icons used for the following track types in the Mix window: Audio, Aux Input, MIDI, Instrument, and Master Fader Audio (waveform), Aux (Down Arrow), MIDI (5-pin connector), Instrument (keyboard), Master (Sigma)
  3. What are some of the track status indicators available in the Edit window? Describe at least three. Task Manager IndicatorFreeze. Solo. Mute.
  4. How many inserts are available on a track in Pro Tools? Why is it important to consider the order in which inserts are arranged on a track? 10 (A-E, F-J). Pro Tools processes inserts in series adding each effect to the previous one from top to bottom
  5. Are inserts pre-fader or post-fader on Audio tracks, Instrument tracks and Aux input tracks? Are inserts any different on Master Fader tracks? Explain. Audio, Instrument and Aux inserts are Pre-fader. Master Fader inserts are post-fader.
  6. Are Sends pre-fader or post-fader on Audio tracks, Instrument tracks and Aux input tracks? Are sends any different on Master Fader tracks? ExplainCan be either pre or post. There are no sends on Master Fader track.
  7. How many sends are available on a track on Pro Tools? 10 (A-E, F-J)
  8. What is the difference between an Output Send and a Bus Send? When would you use each? 1. Output Send: routes a signal out of your audio interface e.g. through an external processor and back into your audio interface, or as a headphone mix. 2. Bus Send: uses internal mix bus to route signal to an Aux Input to be processed by a plug-in.
  9. What level does a send default to when it is first created? How can you change this default? Negative Infinity. SETUP > PREFERENCES > MIXING TAB > disable SENDS DEFAULT TO “-INF”
  10. What is the difference between standard view and expanded view for Sends? What keyboard modifier can you use to toggle between view modes by clicking a Send selector? Expanded View gives access to Send controls for all tracks in the Mix Window rather than an individual track in Standard View cmd+click
  11. How can you prevent a “return” track from muting when one of the source tracks is solo’d? What modifier key is used to enable this function? Solo Safe cmd-click the relevant Aux Return Tracks.
  12. What is the effect of enabling the PRE button in a Send window? What is the effect of enabling the FMP button? PRE = Prefader. FMP = Follow Main Pan
  13. How can you visually determine whether the inverse pan option is enabled for a Send? What button(s) will be highlighted? Both the Link and Inverse Pan buttons will be highlighted (on a stereo Send)
  14. How can you copy a send from one track to another track and duplicate its settings? What considerations might apply? opt-click and drag1. When moving or copying a Stereo Send from a Mono Track to a Stereo Track, any existing Send Pan automation will be dropped without warning. 2. When moving or copying a Stereo Send from a Stereo Track to a Mono Track, the Left Send Pan position/automation data is retained and the Right Pan data is dropped. A warning notification will appear. 3. When moving or copying a Send and replacing an existing Send, all automation on the existing Send will be replaced. A warning notification will appear
  15. Which type of plug-in effects are generally used on inserts? Which are generally used with sends? Why? Inserts are generally used for Gain-based processing (EQ, Compressor, Gate, Expander etc.) (though not always e.g parallel compression) Sends are generally used for Time-based processing (reverb, chorus, delay, etc) – so you can use a common effect for multiple tracks, it also makes more efficient use of processing resources.
  16. What is the Librarian menu used for in a plug-in window? What is displayed in the librarian menu when you first assign a plug-in? Why? Lets you select from available presets for the current plug-in. When a plug-in is first assigned it will have no preset selected and <factory default> will display.
  17. What are some of the uses of a Master Fader? How can you assign a Master Fader to the desired output or bus? They control the master levels of output and bus pathsThey can be used to do any of the following: 1. control and process output mixes. 2: monitor and meter an output level (e.g., a bus or hardware output) to guard against clipping. 3: Control sub-mix levels. 4: Control Effects Send levels. 5: Control levels on submasters (bussed tracks). 6: Apply dither or other inserts to all tracks sent to a common output or bus. Set the AUDIO OUTPUT PATH SELECTOR

PT 110 Lesson 7 Additional Editing and Media Management Review and Discussion Questions

  1. Describe the process of creating a clip loop. What are some of the options available in the clip looping dialogue box? Select an audio clip, MIDI clip or clip group, or select clips across multiple tracks. CLIP > LOOP
  2. What are the two ways that the Trim tool can be used to edit a Clip Loop? 1. If the tool is in the main part of the clip, the entire clip can be trimmed in or out adding or removing loop iterations as needed. (hold ctrl to override Grid mode if active)2. If the tool is in line with a Loop icon all iterations will be trimmed i.e. a loop pattern duration can be cut in half while the number number of iterations is doubled.
  3. How would you go about creating a loop from several separate clips on a track do you want to have repeat as a unit? Make a Selection and create a clip group, then loop this.
  4. What happens to clip loops when you choose the Clip > Ungroup All command? All loop iterations are flattened and all clip groups are ungrouped down to the lowest nested level
  5. What is the difference between Absolute and Relative grid modes? When would you use each? In Absolute Grid mode moving any clip or MIDI note snaps to the current grid boundary. In Relative Grid mode, offsets from grid boundaries are preserved and can be moved according to the current grid unit.
  6. What is the purpose of Layered Editing mode? How can Layered Editing be enabled or disabled? You can stack clips on top of one another while retaining the freedom to move, trim, or delete the topmost clips without losing the underlying material 1. OPTIONS > LAYERED EDITING 2. Click the Layered Editing button in the Edit window toolbar.
  7. Do Audiosuite plug-ins provide real-time processing or non-real-time processing? When might you use Audiosuite processing instead of a plug-in insert? Non-real time. Used to conserve real time processing resources
  8. What does the USE IN PLAYLIST button do in the Audiosuite plug-in window? How can you tell when this option is active? It controls whether the processed audio will replace your selection on the track. When deselected (grey) processed audio will appear only in the Clip List, when selected (blue) the processed audio will appear on the track playlist.
  9. Explain the difference between applying Audiosuite processing as Clip by Clip versus Entire Selection. These two Processing Input Modes determine how the selection will be analysed for processing. Clip by Clip analyses each clip in a selection individuallyEntire Selection analyses an entire selection as if it were a single complete clip.
  10. Why is it important to consider Handle Length when processing with an Audiosuite plug-in? What types of processing to be affected by Audiosuite handles? Audiosuite Handles are not available when the Processing Output Modes is set to Overwrite Files or Create Individual Files while Processing Input mode is set to Entire selection. In such cases processing is applied to the selection only. In contrast, when the Input Mode is set to Clip by Clip and the Output Mode is set to Create Continuous File, Audiosuite handles are applied to underlying audio material outside selection boundaries. If the Input mode is set to Entire Selection, the handles are applied using only the audio exposed within selected clips. EspRelevant for Reverb, Delay.
  11. What modifier key can you use to audition a clip in the Clip List? opt-click
  12. How could you set the Clip List for a session you just opened to display only your newly recorded and edited clips going forward? CLIP LIST POPUP MENU >FIND > INCLUDE SUBSEQUENTLY ADDED CLIPS
  13. What are some options for selecting clips in the clip list? How can you select a range of contiguous clips? How can you select non-contiguous clips? 1. Selecting multiple clips. 2. Selecting Unused Clips. 3. Offline to select all clips that reference files cannot be located on a mounted volume. Contiguous: Click the name, shift-click the last in list. Non-contiguous: Hold cmd
  14. What is the difference between Removing Clips versus Moving to Trash or Deleting clips using the Clear command in the clip list? Remove clears the unused clips from the session while leaving parent files in the Audio Files folder (or their current location). Move to Trash removes clips and moves associated files to the trash. Delete removes the clips and permanently deletes associated files from disk.
  15. What are some options for making selections or subset clips available outside of the current session? What is the purpose of using the Capture command when exporting clips? EDIT > Consolidate Clip. The new clip will be selected in the Clip List. (Optional) Right click on the clip and choose Reveal in Finder CLIP > CAPTURE (cmd+r) lets you create a new subset clip in the Clip List without making a separation on the trackAfter capturing a clip it can be exported as an audio file CLIP LIST POP-UP MENU > EXPORT CLIPS AS FILES (any wholesale subset audio clips in the clip list can be exported in this manner)

PT 110 Lesson 6: Review and Discussion Questions and Answers

How can you access the Grabber? Trim, Selector, GrabberSelector – Position the cursor in the upper half of the clip not near a clip boundary. Grabber – Position the cursor in the lower half of the clip not near a clip boundary(Shortcuts SmartTool (f6+f7 or +f8). Zoom (f5), Trim (f6), Selector (f7)Grabber (f8)Scrub (f9), Pencil (f10)
  2. How can you create fades with the Smart Tool? How can you specify the fade curves that the Smart Tool applies? The cursor in the top quarter of a clip, and within 12 pixels of a clip boundaryFade In: Place the cursor near a clip start boundary, close to the top and drag right. Fade Out: place the cursor near a clip boundary, close to the top and drag left. Crossfade: Place the cursor near a clip boundary, close to the bottom of two adjacent clips, and drag left or right. Fade Curves: SETUP > PREFERENCES> EDITING tab > Fades section
  3. What menu command would you choose to open a Fades dialogue box? What is the associated keyboard shortcut? EDIT > FADES > CREATE. cmd+F
  4. What are some options for previewing crossfades in the Fades dialog box? View First / Left Channel, View Second / Right Channel, View Both. Fade Curves Only, Fade Curves and Separate Waveforms, Fade Curves and Superimposed Waveforms, Fade Curves and Summed Waveforms. nb/ Equal Power slope is best for two different types of material, while Equal Gain is best across similar sounds
  5. What are some options for saving and recalling Fade shapes or configurations in the Fades dialogue box? Save: Librarian menu > SAVE SETTINGS AS. Recall: Click on the Fade preset number, ctrl + preset numberlibrarian menu.
  6. What operations can you use to edit existing Fades on a track playlist? 1. Fades Dialog box: Double click on the Fade graphic with the Grabber, modify the settings in the dialogue box and click OK. 2. Right Click on the Fade graphic, select FADES from pop-up menu3. Keyboard Command: Select the Fade graphic with the Grabber or Selector opt-ctrl+ L or R arrow4. Smart Tool
  7. What is the purpose of the Quantise function in Pro Tools? What are some different ways to apply quantisation? To correct or modify the timing of material1.

  8. What is the purpose of quantising audio clips? How is this different from quantising Elastic Audio? To time align audio. It adjusts audio clip start times (or Sync points). When used with Elastic Audio, quantisation adjusts the location of detected transient events
  9. What feature let you apply changes to a MIDI performance without permanently altering the underlying MIDI data on a track? MIDI Merge.
  10. What types of tracks and clips are affected by Real–Time Properties? MIDI and Instrument.
  11. What are some of the differences between the Real–Time Properties view in the Edit window and the Real–Time Properties floating window? Which allows you to apply clip-based Real–Time Properties? VIEW > EDIT WINDOWS VIEW > REAL-TIME PROPERTIES. 1. In the Edit window Real-time Properties are applied to a whole track, while with the floating window these can be applied to either a whole track, or to selected clips. 2. The Floating window also offers expanded real-time property settings

PT 110 Lesson 5: Using Elastic Audio Review and Discussion Questions

  1. How would you go about enabling Elastic Audio on a track? EDIT window – Elastic Audio Plug-in Selector
  2. Which real-time Elastic Audio processor typically works best for drums? Which typically works best for vocals? Rhythmic. Monophonic.
  3. Which Elastic Audio plug-in provides only rendered processing? When/why would you want to use rendered processing? X-formWhen you want higher quality results, or to reduce processing power, for example in a larger complex session when you’re using lots of plug-ins.
  4. What can Elastic Audio tempo detection determine about an audio file? What are some conditions that will cause no tempo to be detected? It tries to identify rhythmic patterns. Using detected transients Elastic Audio attempts to identify tempo for a file. If tempo detection is successful ProTools will also calculate the file duration in Bars and BeatsFiles with only a single transient (such as a one-shot) will have no tempo detected, nor also will files that contain tempo changes or rubato (rushing/slowing tempo), or files lacking a regular periodic rhythm.
  5. Where are Warp Indicators displayed? What are they used for? 5
  6. What views are available for working with Elastic Audio-enabled tracks? What is each view used for? ANALYSIS VIEW: Edit the detected Event Markers on a track. WARP VIEW: create and edit Warp Markers
  7. Name the three types of Elastic Audio markers. What are the differences between them? EVENT MARKERS indicate audio events ( solid black lines in Analysis view and as grey lines in Warp View – they do not fully extend to the top and bottom of the track) WARP MARKERS anchor audio to the timeline (thick black lines with a triangle at the base) and TEMPO-EVENT generated WARP MARKERS indicate where Elastic audio processing has been applied due to tempo events (grey lines with a diamond at the top)
  8. What are some ways to add Warp markers to a clip? List at least three. WARP VIEW: Grabber Tool double-clickPencil Tool or make a Selection, right-click, ADD WARP MARKER
  9. What is a Telescoping Warp? How does it differ from an Accordion Warp? From a Range Warp? Telescoping Warp lets you stretch/ compress the entire waveform of the clip relative to a start or end pointGRABBER drag any Event Marker to telescope relative to start, opt-GRABBER telescope to end location. Telescoping Warps can be applied to any audio waveform that does not contain Warp markers. Accordion Warp applies Elastic Audio to both sides of a single Warp Marker in a clipThis lets you expand / compress audio equally on both sides of a fixed pointAdd a single Warp Marker at the point you want anchored to the timeline, then with the GRABBER drag any Event Marker on either side. Range Warp applies Elastic Audio between two fixed points in a clip. In Warp View create a Warp Marker at the start point, and a second marker at the end point. Create a third marker between the first two and drag to warp the underlying audio while the audio outside the boundary markers remains unaffected.
  10. What is the effect of quantising a selection on an Elastic Audio-enabled track? What happens to the Event markers within the selection? Quantising allows you to align audio events to tick-based information (Bars | beats, sub beats) based on the session tempo. Event markers are used as control points. Those that are closest to the specified quantise grid are promoted to Warp Markings and are moved to the grid.
  11. Why is it important to have accurate Event markers in your clips when applying Quantise operations on Elastic Audio-enabled tracks? Because it is they that become aligned to the grid and hence form the basis of the quantise operation.
  12. After enabling a track for Elastic Audio, how would you enable the track to update dynamically to match any subsequent tempo changes you make in the session? First Enable Elastic Audio, and then change the timebase of all desired audio tracks from samples to ticks.
  13. What are some ways to improve the quality of audio that has been warped with Elastic Audio processing? 1. Having accurate event markers (Analysis View), 2. Adjusting Event sensitivity or 3. Using rendered Elastic Audio processing (X-form) – note that X-form processing can take some time!
  14. What is meant by Event Confidence? How can Event Confidence be used to eliminate false transients when applying TCE processing on Elastic Audio-enabled tracks? Each Event Marker is assigned a confidence level based on the relative clarity of the associated transientCLIP > ELASTIC PROPERTIES window, or right-click the clip and select ELASTIC PROPERTIES or opt- 5 alphanumeric keypad.
  15. What are two ways to apply Elastic Audio pitch transposition? What are some applications for using each option? 1. ELASTIC PROPERTIES WINDOW. Apply a pitch shift across selected audio clips. 2. EVENT OPERATIONS > TRANSPOSE WINDOW To create a transposition across multiple tracks including pitched MIDI data. (Pitch transposition is not supported for Monophonic or Varispeed Elastic Audio algorithms)

PT 110 Lesson 4: Review and Discussion Questions and Answers

  1. What timebase do Audio tracks to default to? MIDI tracks? Instrument tracks? By default Audio tracks are sample-basedMIDI and Instrument tracks are tick-based
  2. Which ProTools timescales are absolute? Which are relative? What is the difference between absolute and relative timescales? Sample-based are absolute, tick-based are relative. Absolute timescales remain static and reference fixed measures of time (Samples, Minutes:Seconds, Timecode, Feet+Frames). Tick-based tracks conform to session tempo and reference the relative timescale of Beats| Bars
  3. How do audio clips respond to tempo changes on a sample based track? How do they respond if you change the track to tick- based (without using Elastic Audio)? They will remain static on a sample-based track – if you change an Audio Track timebase to tick-based, the start of the audio clips will become fixed to the Bars |Beats ruler and the start of the Clips will move relative to the sample timeline when tempo or meter changes occur
  4. Pro Tools provides 960 ticks per quarter note; how many ticks does it provide per half note? How many per eighth note? 1920. 480
  5. Why might you want to render a MIDI performance as audio? What are some of the available options for rendering a virtual instrument’s output to an audio file? To make edits or processing in a way that you can’t with MIDI, to save processing power1. Drag-and-Drop rendering2. Track Freeze
  6. What are some of the different options available for viewing data on MIDI and Instrument tracks in the Edit window? What kinds of operations can you perform in each view? Blocks, Clips view – displays MIDI data for arranging and assembling. Notes View – displays MIDI notes as small individual segments in piano roll style of editing. Velocity View – displays MIDI note attack velocity. MIDI Volume, MIDI Pan and Control Graph views – display automation playlists (Pitch Bend, Aftertouch, Program Change, SysEx) and CC Control line graphs (Mod Wheel, Breath, Foot Control, Expression, Sustain).
  7. Where are the MIDI input and output controls located for MIDI tracks in the Mix window? Where are they located for Instrument tracks? For MIDI: VIEW > I/O view – MIDI INPUT SELECTOR and MIDI OUTPUT SELECTOR. For Instrument: VIEW >Instrument view
  8. What does the MIDI Thru option do? How is it enabled? It allows incoming MIDI data to pass through a track to its MIDI output. OPTIONS > MIDI Thru
  9. What is the Default Thru Instrument setting used for? How can you change the Default Thru Instrument setting? It allows you to preview or audition any MIDI clip in the Clip ListSETUP > PREFERENCES > MIDI tab
  10. What keyboard modifier would you use when clicking on a MIDI clip in the Clip List to audition it? What is required for this process to play sound? opt-click. SETUP > PREFERENCES > MIDI tab – Default Thru Instrument – Follows First Selected MIDI track. Then in EDIT or MIX window select the MIDI track you want to to use as sound source.
  11. How is editing MIDI different from editing audio? How are MIDI notes affected when deleting a selection or trimming a clip compare to how audio waveforms are affected? When cutting, clearing or trimming a selection that includes a MIDI note’s start point the entire note is removed. Conversely, when cutting, clearing or trimming a selection that includes the note’s end point but not its start point the entire note remains and overlaps the end of the clip. When removing and placing MIDI clips with overhanging notes the notes move with the clips. When placing a MIDI clip with overhanging notes next to another clip the overhanging notes extend into the adjacent clip.
  12. What are some of the functions of the Pencil Tool when editing MIDI notes? In many ways the Pencil [f10] is a universal tool for MIDI.

  8. What keyboard shortcut can you use to toggle pre-/post-roll on and off? cmd+K
  9. What are alternate playlists on Pro Tools? How can playlists be useful when recording multiple takes? They enable multiple versions of a track, each containing a different arrangement of clips. They allow you to retain each recorded take on a separate instance of the track, which can help with choosing the best take later on. They can also be used for comping.
  10. When might you use the Pro Tools Preferences setting called Send Fully Overlapped Clips to Available Playlist While Recording?

By selecting just that section and separating the clip EDIT > SEPARATE CLIP > AT SELECTION (cmd+E)
  11. What are some differences in the way audio and MIDI clips are created when recording? How do you go about enabling loop recording for audio or MIDI? Audio: ProTools creates a single file that comprises all takes. Takes appear as individual subset clips in the Clip List and are numbered sequentially. If an audio record pass is interrupted before the midpoint of the loop the entire take is disregarded. MIDI: New clips are created each time a new record pass begins. However if no MIDI is received no clip is added. In contrast to audio, if a MIDI record pass is interrupted mid-take, the entire clip is retained regardless of where the pass stopped. 1.Make timeline selection 2. OPTIONS > LOOP RECORD, or right click RECORD button (Shortcut opt-L, or [5] on alphanumeric keypad) (Ensure LINK TIMELINE AND EDIT SELECTION is selected)
