Tap the automation button to toggle between its two states. Alternatively, press Read/Write
(MPC X, MPC Key 61) or Automation (MPC Key 37).
When set to Read (R), the audio track will read automation data but will not record any additional
automation over it. (Think of this as a protective feature to prevent accidental changes to your
automation while recording.)
When set to Write (W), the audio track can record automation. (If you have any Q-Link knobs
assigned to automatable parameters, make sure not to touch any accidentally while you are
recording.)
Tip: You can quickly set all programs and audio tracks to the same automation by tapping the
global automation button in the upper-right corner of the screen. See
Automation to learn about this.
Press and hold Shift and tap the automation button to disable program automation.
Alternatively, press Shift+Read/Write (MPC X, MPC Key 61) or Shift+Automation (MPC Key
37). When off, the audio track will ignore automation data.
Important: If you have already recorded automation and turn it off, the audio track will still use
the effect and its parameter values at the point where you turned it off.
Adjust the pan knob or level slider to change the panning or level of the track.
Tap the Record Arm button or press Rec Arm (MPC X) to record-enable the track. When you
begin audio recording, the audio signal will be recorded to this track.
Tip: You can select multiple tracks in the Rec Arm tab by pressing and holding Shift and tapping
each pad on the screen. You can also do this in the Track View by pressing and holding Shift
while tapping the Arm button to each track. You can also set the Rec Arm preference to either
Single or Multi in the Preferences.
