There isn't one. But it would be a nice idea to start a thread, that
contains only postings that contain one question and its answer(s) per
posting. This thread should not contain any discussions.
In regards of your problem: Alan asked the right question already. The
key contacts are the most likely cause for the problem. You simply can
test it by shorting the matrix-contacts on the KLM356, connector 22 (you
may use a diode for it, but you don't have to).
You may check the VCO outs with a scope (the easiest points are the
waveform selectro switches). There should be atleast some low frequency
signal.
Next thing: check whether the switch contacts at the trigger-In socket
do give contact! Also the polarity switch might be corroded (in this
case the voice LEDs should be lit when you play, but you won't hear
anything nevertheless).
