PROGRAM CHANGE MODE

A Program Change, often referred to as a Patch Change, is a MIDI message used for sending data to

devices to cause them to change to a new program. This allows you to tell a hardware or software device

which sound to play. For example, if your MPK25 is controlling a piano patch on your DAW or an external

device, using a Program Change command allows you to easily switch to a synth patch.

There are two different types of Program Change messages on the MPK25:

PROG CHANGE – This event will transmit a regular Program Change message (0-127) to your DAW or an

external device, allowing you to switch between 128 different program banks.

PROG+BANK – This event transmits a Program Change message (0-127), along with a Bank L (Least

Significant Bit) Change message (0-127) and a Bank M (Most Significant Bit) Change message (0-126),

which allows access of up to 16384 different program banks. You can use PROG+BANK if your DAW or

external device supports LSB and MSB.

To enter Program Change mode, press the [PROGRAM CHANGE] button. Then, turn [VALUE] dial to

select either a PROG CHANGE or PROG+BANK event.
