Making mono hat keys in a poly drum map

[cookseytalbott]

Can any one give me some guidance on making the hat keys, F# G# and A#, be monophonic in a regular GM drum map instrument where the rest of the samples are mapped as polyphonic ?

I would split all 3 hihat notes to another track then load another channel in Mach5.
Set that MIDI channel to the same.
You can pan it to one side or set the output to another bus.
