I guess it looks like the only way to go
is to use a dedicated footswitch like the
Ketron you mentioned, or
the Roland FC-7 (that works with the Roland RA-800/RA-95)
which has a separate switch for:
Start/stop
Intro
Advanced/Standard
Fill 1
Fill 2
Main/Variation
Ending;
because I cannot send sysex from the drumKat
controller. The drumKat can also generate
up to 4 note chords, but I also have a remote
Novation keyboard to input chords.
I was hoping for a module that could do what
I described, just using it and the drumKat;
instead of a manufacturer specific dedicated footswitch.
