EDITING KNOBS

The knobs on the MPK25 are controllers which can be set to transmit Control Change or Aftertouch information. In addition, the knobs may also be assigned as an Increment/Decrement function. Their default operation is to transmit Control Change information when used.

What is Control Change?

Control Change refers to the use of MIDI Continuous Controller data. Continuous Controller

(CC)data are MIDI messages capable of transmitting a range of values (0-127) and are often used for controlling volume, pan and other parameters on your DAW or sound module.

What is Aftertouch?

Aftertouch refers to MIDI information sent when pressure is applied to a pad after it has been struck, and while it is being held down. Aftertouch is often used to control volume, vibrato and other parameters. On the MPK25, the knobs can also be assigned to transmit Aftertouch information.
