Although a regular program can have up to 3 layers, the K2000 can create programs that have as many as 32 layers! These are called Drum Programs because a typical use for a program with that many layers would be for drums, but they can have any sounds in them - not just drums. (And a program containing drum sounds can be three layers or less, so it would not be considered a Drum Program).

The K2000 can play only one Drum Program at a time. A Drum Program can only be played on the MIDI channel designated as the Drum Channel, which you can set. If you select a different MIDI channel other than the one you've designated for the drum channel and scroll to a Drum Program you will notice a ( ) around the program name and no sound will play. To see the selected MIDI drum channel assignment press the Master button; you will see DRUMCHAN and the MIDI channel # that is currently selected.
