Akai MPC 60, Operator'S Manual, Page: 206 / 228

NOTE: Because "NONE" is the default setting (for highest timing
efficiency), it is normal that no "note on" messages will be sent out over
midi when drum tracks play. If you are using an external drum generator in
addition to the MPC60's internal sounds and therefore want these messages
to be sent out while drum tracks play, you must select "DRUM NOTES" in
this field.
The two remaining fields in this section are together used to determine
which midi note numbers are sent out when each of the internal drums play.
To view or change the assignments, select the desired drum in the DRUM
field, then view or change its note number assignment in the PLAYS
NOTE field (you can also set the note number by playing a key on the midi
keyboard). The default settings are the same as for the ASSIGN
INCOMING NOTES TO DRUMS section, except in reverse.
The "OTHER" section:
This third section of the screen contains only one field, MIDI DRUMS
CHAN, an abbreviation for "Midi drums channel". This field selects the
midi channel over which the internal drum generator receives its "play
note" commands from the internal sequences (or from another midi
source- see note below).
The setting of this field is very important because THE ONLY WAY OF
DETERMINING WHETHER OR NOT A TRACK IS A "DRUMS"
TRACK OR A "NON-DRUMS" TRACK IS WHETHER OR NOT THE
TRACK'S MIDI CHANNEL MATCHES THE NUMBER IN THIS
FIELD! Also, any track assigned to this channel is a drums track, regardless
of the track's output jack selection (A, B, C, or D). For further information
on this subject, read the section entitled "How to assign "drums" and
"non-drums" tracks" in the "Recording sequences" section of the manual.
