>First, hello to Tony (master of the 303) A.
More of a slave really :-) Actually, I don't have one, not a real one
anyway.
>maybe you can answer last weeks question about a 303 audio output being
used as a GATE signal?
I have never tried it, but it perhaps could if you used the headphone
out. You normally need a couple of volts to trigger a gate. But, it
wouldn't be clean trigger at all. Hasn't the TB got a gate output to use
anyway. But I have missed most of the thread here...
As for bi-colour LEDs, love them to bits. Its always best to put them in
the feedback path of an op-amp, that way you don't get any dead bits for
low level signals. The problem is just how much current do you want the
little critters to have. I reckon 5 to 10mA is about the best to have
reasonable brightness and not too much current drain. Hard to see
(groan) how you could use one on a standard unipolar ADSR though. But we
could always try.
