VAST programs with more than three layers are known as drum programs, as shown in the 
following diagram. Drum programs can use any sound you like, but the most common use for 
programs with more than three layers is to create a number of different sounds across the 
keyboard—which is perfect for combinations of percussion sounds (hence the name). For drum 
programs, the info box simply indicates the number of layers in the program—in this case, 26.

KB3 Programs
The architecture of KB3 programs is different from that of VAST programs. KB3 programs don’t 
have layers; they rely on oscillators that mimic the tone wheels used in many popular organs. 
Consequently, the info box shows only the waveform used in the program.

Because of their architecture, KB3 programs require different processing within the K2661, and 
they don’t work on “regular” channels. They require a special channel to handle the KB3 
program’s voices. You can choose any of the 16 MIDI channels to be the KB3 channel, but you 
can have only one KB3 channel, and KB3 programs play only on that channel (VAST programs 
work just fine on the KB3 channel, by the way).
By default, Channel 1 is designated as the KB3 channel (you can change it in Master mode). If 
the current channel isn’t the same as the KB3 channel, and you select a KB3 program, you won’t 
get any sound, because a non-KB3 channel can’t handle a KB3 program.
