Editing MIDI Events and Continuous Controllers (CC)
Controllers, RPNs, NRPNs, and Automation Data
Controllers, RPNs, NRPNs, and
Automation Data
SONAR projects contain a lot more information than the notes and digital audio files that are at the
heart of your work. Controllers, RPNs, and NRPNs (xRPNs, for short) are special types of events
used by MIDI software and hardware to control the details of how MIDI music is played. Automation
data are used to adjust volume, pan, and other parameters of MIDI and audio tracks on the fly while
playback is in progress.
SONAR lets you enter or edit controller, xRPN, and automation data in several ways:
• Using envelopes in the Track view
• Using the Piano Roll view and Inline Piano Roll view
•Using the Insert > Controllers command
• Editing controller events in the Event List view
Editing data in the Track view’s Clips pane or the Piano Roll view gives you great flexibility. You can
examine the controllers in graphical form and edit them even while recording or playback is in
progress. This means you can loop over a portion of your project and hear any change you make on
the next loop.
For more information about automation, see the online help topics “Automation,” and “Mixing.” For
more information about the Event List view, see “The Event List View” on page 512.
Velocity From 0 to 127 From 127 to 0 Inverts the velocity values (makes loud notes
soft, and soft notes loud)
Duration From 0:01:00 to
0:02:000
From 0:01:000 to
0:01:000
Converts all notes that are between a quarter
note and half note in length, and makes them
all quarter notes
Channel From 1 to 1 From 2 to 2 Changes all events on MIDI channel 1 to MIDI
channel 2
Channel From 1 to 16 From 4 to 4 Reassigns all events to MIDI channel 4
Note: MIDI envelopes you create in the Piano Roll view and MIDI envelopes you create in the
Track view Clips pane are actually separate envelopes, even if they control the same parameter.
Both kinds of envelopes are visible in the Clips pane, and should generally not be used to control
the same parameter. You can convert Piano Roll view envelopes to Track view envelopes by
selecting the time range and tracks that the Piano Roll envelopes occupy, and using the Edit >
Convert MIDI To Shapes command.
