Playing a Virtual Instrument and Recording MIDI

 This article includes the following:

Instrument Track overview

 An Instrument track can combine a LUNA Instrument or Audio Units instrument plug-in and MIDI data. You can record MIDI on an Instrument track. An Instrument track can record MIDI data alone with no audio or Instrument plug-in.

Creating an Instrument track

You record MIDI data, instantiate LUNA Instruments, and use other instrument plug-ins on an Instrument track. 

Tip: To instantly create a stereo Instrument track with Shape instantiated, choose Track > New Instrument, or press Shift+Command+I.

To create an Instrument track:

  1. In the Tracks browser, click the plus (+) next to Tracks and choose Instrument from the contextual menu. If the Create New Tracks dialog is already open, choose Instrument from the Type drop menu.
  2. Type the number of tracks to create, choose the format (Mono or Stereo), and type a name for the track or tracks.
  3. From the INST drop menu, choose a LUNA Instrument, an Audio Units instrument plug-in, or choose None to record MIDI alone or to use an external MIDI instrument.
  4. Click OK to create the tracks, or Cancel to stop track creation. 

Choosing a MIDI controller

LUNA will accept MIDI input from all MIDI devices that are recognized by the macOS Audio MIDI Setup app. If you have multiple MIDI devices, you can choose which MIDI input the instrument track will use to trigger the instrument.

On an Instrument track in the Mixer or on an Instrument track Focused in the Timeline, click the MIDI In row, and choose the MIDI Input to use for the instrument. Press Esc or click the close button to close the MIDI In browser.

Note: A track that is Input enabled responds to an assigned MIDI controller only when the track is selected. However, record-enabled tracks respond to assigned MIDI controllers when the tracks are not selected.

Using MIDI Keyboard Mode to input MIDI

If you don’t have an external MIDI controller, or you prefer to use the computer keyboard to input MIDI notes, you can use MIDI Keyboard Mode. MIDI Keyboard Mode maps MIDI notes (1-⅓ octave from C to E) to keys on the computer keyboard, which you can use to perform MIDI recording. 

When you enable MIDI Keyboard Mode, you can enter MIDI notes when monitoring or recording by pressing keys on the computer keyboard. MIDI Keyboard Mode provides the ability to change the octave of the keyboard and to set a velocity level for MIDI notes you input with the computer keyboard. 

Note: Any single-key commands that use one of the notes on the MIDI keyboard will not work when MIDI Keyboard Mode is enabled. For example, “E” (Frame Selection) and “F” (Create a Fade) are not supported when MIDI Keyboard Mode is enabled. When available, use the modifier-key version of such a key command (for example, Command+F to create a fade). There is no modifier key for the “E” command.

To enable or disable MIDI Keyboard Mode:

  • Press Option+Command+M, or 
  • Choose View > MIDI Keyboard Mode, or 
  • Click the MIDI icon under Workflows at the top of the screen to enable the MIDI Workflow, then toggle MIDI Keyboard Mode (for more information about workflows, see Using Workflows).

To play notes with MIDI Keyboard Mode:

  • Press the keys as indicated in the MIDI Keyboard map in the workflow bar at the top of the screen.
  • To change the octave over which the keys send MIDI notes, press Z on the computer keyboard to lower the range one octave. Press X to raise the range one octave. You can also click the Up and Down arrows under Octave in the Workflow area at the top of the screen.
  • To set the MIDI Note velocity that each key press sends, press C on the computer keyboard to decrease the velocity, or D to increase the velocity. You can also click the Up and Down arrows under Velocity in the Workflow area at the top of the screen, to raise or lower the velocity one step at a time.

MIDI Merge or MIDI Replace

Before you record, decide whether you want to use MIDI Merge or MIDI Replace. 

  • With MIDI Merge (select Transport > MIDI Merge or 9 on the Numeric Keypad), the MIDI notes you play are combined with the existing notes over which you record. MIDI Merge is useful, for example, if you want to build up a track like a drum part by playing in separate drums on successive record passes.
  • With MIDI Replace (deselect Transport > MIDI Merge or 9 on the Numeric Keypad), the MIDI notes you play replace those in the selection over which you record. MIDI Replace is useful when you want to correct a part, or play a part differently, without keeping the previous part.

Recording on an Instrument track

When you record on an Instrument track, ARM mode is not required to get the fastest response from LUNA Instruments or third-party Audio Units instruments, because the buffer is the same in both cases. However, if you use UAD plug-ins to process audio on the Instrument track or on a bus, you should enable ARM mode to get the lowest possible latency. In ARM mode, you cannot use Audio Units insert effect plug-ins on any record-enabled track.

To record on an instrument track:

  1. In the Tracks browser, click the plus (+) next to Tracks and choose Instrument. If the Create New Tracks dialog is open, from the Type drop menu, choose Instrument.
  2. Type the number of tracks to create, choose the format (Mono or Stereo), and type a name for the track or tracks.
  3. From the INST drop menu, choose a LUNA Instrument, an Audio Units instrument plug-in, or choose None to record MIDI alone.
  4. Click OK to create the tracks, or Cancel to stop track creation. 
  5. In the Focus channel or Mixer, click the Input mixer row. The Input browser opens.
  6. Choose the MIDI input to which your controller is connected. MIDI devices recognized in the macOS Audio MIDI Setup app are available here. You can also play and record MIDI notes using the computer keyboard. Select View > MIDI Keyboard Mode from the menus, or press Option+Command+M to use the computer keyboard to input MIDI notes with the keyboard.
  7. Click the Input enable button or Record enable button on the track or Focus channel (Timeline view) or on the channel (Mixer view). The Input enable button allows you to monitor the Instrument or audio source when the Instrument, plug-in, or device is triggered with the MIDI Input source. The Record enable button allows you to record MIDI data to the Instrument track, when you click Play and Record on the transport.

  8. If you are using UAD plug-ins in the Record FX or standard inserts on the Instrument track, enable ARM mode for the lowest possible latency.
  9. Choose whether to use MIDI Merge or MIDI Replace.
  10. Click Record and Play on the transport or Command+Spacebar to record MIDI.
  11. Click Stop or press the Spacebar to stop recording.
 

Recording MIDI and playing back audio from an external MIDI instrument

You can record MIDI from an external MIDI instrument, while monitoring the audio from that device or another device. By sending the MIDI output from an Instrument track to an external MIDI hardware device, for example a synth or a drum module, you can monitor or record the audio from this device on an available audio input. 

To trigger and record MIDI and monitor or record audio from a MIDI sound generator:

With this task, you send MIDI data from an Instrument track to an external MIDI device, and monitor or record the audio output from that device on a separate audio track. Use this task to record a synth or sound module to an audio track, while retaining the ability to edit the original MIDI performance data. 

Before you do this task, create a mono or stereo audio track, and connect the synth or sound module to an Apollo hardware input or stereo input pair.

  1. In the Tracks browser, Timeline, or Mixer, select the Instrument track on which you have recorded MIDI. 
  2. In the Mixer channel or Focus channel for the track, click the MIDI Out mixer row. The MIDI Out browser opens.
  3. Choose the MIDI Output to which you want to send MIDI data. MIDI devices recognized in the macOS Audio MIDI Setup app are available here, as are all Instrument tracks in your session. Choose the MIDI device that you have connected as the audio generator.
  4. On the audio track, click on the Input slot, then from the Input browser, choose the Apollo hardware input or stereo input pair to which the device is connected.
  5. Press the Input enable button to monitor the audio source when the instrument is triggered with the MIDI output. 
  6. Press the Record enable button on the Instrument track to record MIDI data. Press the Record enable button on the audio track to enable audio recording.
  7. If you are using UAD plug-ins in the Record FX or standard inserts on the Instrument track, enable ARM mode for the lowest possible latency.
  8. Select the range you want to record, or place the playhead where you want to start recording. 
  9. Press Record then Play (Command + Spacebar). 

Audio generated by the synth or sound module is recorded to the audio track and the MIDI source data is recorded to the Instrument track..

Note: If the external MIDI controller is the same device as the MIDI sound generator (if it’s a MIDI keyboard controller with built-in sounds), be sure to disable the MIDI keyboard’s “MIDI Local Control” setting to prevent doubled MIDI notes. 

Overdubbing and Looping on an Instrument track

You can overdub directly on a MIDI clip, starting wherever you place the playhead, or in a range that you select. You also have the option to loop record, which creates separate Versions (which are labeled as Takes when loop recording) for each complete loop recording pass.

Before you record, decide whether you want to use MIDI Merge or MIDI Replace.

  • With MIDI Merge (select Transport > MIDI Merge), the MIDI notes you play are combined with the existing notes over which you record. MIDI Merge is useful, for example, if you want to build up a track like a drum part by playing in separate drums on successive record passes.
  • With MIDI Replace (deselect Transport > MIDI Merge), the MIDI notes you play replace those in the selection over which you record. MIDI Replace is useful when you want to correct a part, or play a part differently, without keeping the previous part.

To record over existing MIDI without a selection:

  1. Click within the track or in a ruler above the tracks to place the playhead where you want to start recording.

  2. To use Pre-roll (listen to the existing track for a specified period of time before you start recording), Option+click to the left of the playhead on the Bars and Beats ruler.

    qs-optionclick-pre-roll.png

  3. Record-enable the MIDI track.
  4. Press Record then Play (Command+Spacebar), and begin playing. MIDI records from the playhead. If you set a pre-roll amount, the system plays the pre-roll section before recording starts.
  5. Click Stop or press the Spacebar to stop recording.

To record over a MIDI selection:

  1. Hovering the cursor over the bottom solid-colored border of the audio clip, click and drag to make a selection. The selection snaps to the grid, if Snap is enabled.

    midi-selection.png
  2. To use Pre-roll (listen to the existing track for a specified period of time before you start recording) Option+Click to the left of the playhead on the Bars and Beats ruler. To set post-roll, Option+Click to the right of the selection on the Bars and Beats ruler.

    qs-optionclick-pre-roll.png

  3. Record-enable the track.
  4. Press Record then Play (Command+Spacebar), and play your MIDI controller or the computer keyboard. MIDI records from the start of the selection, and stops recording at the end of the selection. If you set a pre-roll amount, the system plays the pre-roll selection before recording starts. If you set a post-roll amount, the system plays the post-roll selection after recording completes.

The MIDI you record is either merged with the existing MIDI, or replaces it, depending on whether MIDI Merge is enabled.

 

Loop recording MIDI

When you loop record, you either replace a section of a track that you select with one or more recorded takes, or you record multiple merged passes. When LUNA reaches the end of the selection, the transport returns back to the start of the selection, and records again. Each complete record pass is saved as a Take. To show recorded Takes, click the Versions button at the top of the Tracks area.

On a MIDI track, takes are separate from track versions. Therefore you can switch between Takes of one clip, and the selected track version and any other clips associated with it, remain. 

To loop record (with MIDI Merge):

  1. Select Transport > MIDI Merge.
  2. Make a MIDI selection and click the Loop Play / Record button.

To loop record (with MIDI Replace):

  1. Deselect Transport > MIDI Merge.
  2. Make a MIDI selection and click the Loop Play / Record button.
