OK OK this is REALLY interesting!!
Paul, regarding your comment about swapping the data messages for the drum firing - does this mean then, that it would be possible to exchange the data lines, so that, where there would normally be a hand clap in a rhythm, you can get it to be the cymbal?
I ask this in relation to my SK-8 (almost identical to the SK-5 circuit).
The SK-8 doesn't have the drum sound pads - but you can still access these sounds individually from the matrix grid, and put external switches to trigger them, just like the SK-5 pads.
The drum sounds , in this case, on the SK8 are kick, snare, hihat, handclaps.
I would like it to be: kick, snare, hihat, cymbal - because I can use the cymbal as an open hihat.
Since I have these 4 drum lines and the keyboard keys MIDI'd with a Highly Liquid MIDI SK board, it will then mean that I can finally access the cymbal over MIDI, and sequence my own rhythms with the cymbal (open hihat).
Below is the matrix table for the SK8, if that helps. Where the matrix table refers to "base" that means kick drum, not bass sound.
Is this possible?
cheers, graham
