Rusty, in the manual it says that the DRUMs can not be over written/ changed,only use the standard kit. This is the same for both PK5 and PK5A pedal boards.
PK5A manual has better info........... etc........
[6] DRUMS mode
Press the DRUMS selector [6] to switch the PK-5A to
DRUMS mode.
In keeping with standardized usage
(GM and GS, for example), the PK-5A transmits on
MIDI channel �10� when this mode is selected. You
can change this, however (e.g. to �16� in order to
control the M.Drums part of Roland arranger-type
instruments).
After selecting DRUMS mode, you can use the
PK-5A�s pedals for �drumming�.
In DRUMS mode [6], the following functions are
available (FUNCTION section):
[9] FACTORY SET (DRUMS)
After pressing the FACTORY SET selector [9] (the
corresponding indicator lights), 13 note numbers
can be transmitted for triggering an external
instrument�s Drum Set. The note numbers
assigned to the pedals in this way represent the
PK-5A�s factory set. This FACTORY SET cannot
be overwritten.
