[sdiy] Keyswitches

[Tim Johnson]

Hi Group,
How about a dumb newbee question to brighten your day?
I was wondering if anyone had or knew of a circuit that made use of ONE set 
of switches to generate both, the C.V. and trigger signal. The organ I am 
going to use for my project only has one switch per key.
I thought I saw a circuit that did this by superimposing an A.C. signal on 
the ladder resistors. Another circuit detected the A.C. signal (or D.C. for 
that matter) and generated the trigger while sending the ladder D.C. to the 
C.V. circuits.
Am I crazy of would this work?
Also what would involved in making it play more than one note at a time?

Thanks

Jim
