The MBD1 is 28‑note polyphonic and 8‑part multitimbral, with MIDI channel 10 dedicated to providing drum/percussion sounds. There are actually 17 different programs, the first 11 of which are different drum kits (though some of the percussion sounds are common to each kit). Kits 12 to 15 are similar kits but with missing kick, snare, hi‑hat or tom parts, enabling you to use these kits in conjunction with the more specialised drum sounds found among the regular synth voices.
