You now have a new MIDI region on each of the record-enabled tracks.
There are two operating modes available for simultaneous recording of multiple MIDI
tracks: layer recording and multiplayer recording.
• When layer recording: Incoming MIDI events are sent to all record-enabled MIDI tracks.
You can listen to all selected instruments before, and during, recording.
• A MIDI region is created on the selected track after recording.
• Aliases of the MIDI region on the selected track are recorded on the other tracks.
The advantage of this approach is that any subsequent edits to the “parent” MIDI region
will affect all aliases, ensuring that all layered tracks remain identical.
• When multiplayer recording: Incoming MIDI events are distributed to the various
record-enabled tracks, in accordance with transmitted MIDI channel numbers.
• The channel of the incoming event must correspond to the channel of a
record-enabled track for this functionality to work.
• If no track with a corresponding channel number is found, the event will be routed,
and recorded, onto the selected track.
You should ensure that each of your MIDI controllers transmit on different channels. If
this is not possible, simply use different inputs on your MIDI interface and change the
MIDI channel of each input, using a transformer object between the Physical Input and
Sequencer Input (see Physical Input Objects and Sequencer Input Objects).
To switch from the Layer recording mode (default) to the Multiplayer recording mode
µ Choose File > Project Settings > Recording, and select the “Auto demix by channel if
multitrack recording” option.
Recording Multiple MIDI Tracks Successively
You can record several MIDI regions on individual tracks when in Cycle mode.
