[sdiy] learning from early drum machines?

[David G. Dixon]

Tom (and Dan),

What about using a pcb-mounted MO tactile switch and a flip-flop?  With a
backlit LED in the switch, this would be very cool, very intuitive, and I
think it would also be pretty cheap (depending on the switch).

I don't see any advantage to using jacks and plugs over using a grid  
of latching switches. Ideally, you'd want to find a big bag of  
surplus switches for not much money. Then you could arrange a row of  
switches for each sound, and just press down the ones where you want  
a beat. I think Dan has definitely got the right idea.
