MOTM

Sorry Paul, I really didn't want to stir up anything big here and maybe 
"fatally" was too much.  But this was a list where I thought we can talk 
openly about the MOTM, good or bad.  It was your comment "However, I don't 
forsee a reason to redesign. It *is* a cheap, simple circuit." that made me 
think you weren't going to address the problem.  It may be a cheap and simple 
circuit, but it's a necessary one.

Maybe you haven't read everything I've written clearly.  It's only problem #1 
that's a problem.  #2 and #3 I mentioned can be be solved by keeping the 
sustain level below 8 or it looks like by changing R9 if one desires.  #4 is 
just an observation when an EG is patched to the VCA.  I think it's the VCA 
starting to close down when the voltage gets low that I'm hearing and not the 
EG itself.

I'm not wanting a major redesign, but a possible optional and simple fix that 
those of us can do without any parts from you.  As for those who are making 
light of the whole thing by saying in future it may be something sought after 
and such, no, it's not something you want.  The output should never go above 
~4 to 5 volts.  Perhaps driving short fast release sounds from a sequencer, 
doing soundscape type effects, chaos patches, or maybe in a thousand other 
settings the envelopes are just fine and that's why strangely nobody else has 
come across it.  But to a keyboard player like me they are an issue.  I'm 
seeing it like 30% of the time.  And I need to patch velocity into my patches 
which will only aggrivate the situation.  It's just very frustrating to keep 
patching up sounds, that as soon as I start playing they change on me.

It's not precission I need, just no voltages shooting up over 6v when 
playing.  For my current application I have others I can use.  The 800 bug is 
the only thing that bugs me about the MOTM, I love everything else.  Don't 
let me persuade any of you away from it.  I tried my one Synth.com ADSR and 
the problems it's giving me make the MOTM-800 look good.
