Re: [motm] Annoying MOTM envelope behavior

It's all very strange.  I was going by my ear on #3.  I just don't seem to 
get a hard attack but I haven't digitized it to see just how fast it is.  I 
did however try your UEG for comparision even though it's not a typical ADSR 
and I didn't experience any of these problems.

a) Are you *sure* these are the "Rev B" EGs (with the TRIG wire mod)?

c) Are you using the TRIG input as well?

a) I bought all my 800's after the trig mod, so yes, they are all Rev B.  I 
have a total of 6 of them.  Just to be sure I didn't make a global mistake 
when I built my first batch, I just connected one from my second batch and it 
behaves the same.  Since Tony or Encore also sees these things, I have to 
rule out a mistake on my end.  That's the confirmation I wanted.  I surprised 
the rest of the list is silent.

b) My gate source is the Kenton Pro-2000.  It's set to a 5v gate, but behaves 
the same when set to 15v.

c) I'm not using the trigger input.

It's almost as if I'm playing on a touch sensitive keyboard when using my 
MOTM.  How I play affects the ADSRs and thus the brightness and loudness of 
the synth.  That of course shouldn't be the case.
