   oh, I was trying it before but I didn't realize it's not working (it 
didn't complain though, just no output) because I did connect 64:0 to 
65:0, once I detached them it works. thanks!

   sort of qualifies:-) I'd like something that would try to interpret 
it and print out the result (as in note on, note off etc.)

   I see e.g. 99 2F 51 where the second number differs for different 
pads and the last number is up to about 70 (harder hit = higher number). 
But I can't hear anything.

   when I dump one of the demo songs the volume has about same values 
and I can hear those... however it also sends 89 xx xx and EC xx xx 
messages, there's also number of F8 messages (clock?)

   any ideas how to further debug these? Do I need to check midi 
protocol and go from there?

   thanks,
