MOTM

(grits teeth):

a) there is NOTHING WRONG with the '190 VCA.

b) I've sold over 180 '190s, perhaps 4 people have said something.

c) I've looked at the outputs with my $10,000 digital scope looking for obvious 
'spikes' or DC shifts. Nope. I've run FFTs. I've duplicated "clicking" by 
hand-editing waveforms in SoundForge and playing them back on crappy PC 
speakers. The *same file* makes *no clicks* on my Event 20/20s.

d) What you may want to try is increasing C9 on the '800 to like 10uf non-polar. 
This will increase the overall ADR times, and you may find that on the lower end 
of the scale (from 0 to 2) it's easier to find an Attack time that is more 
'forgiving'.

e) you may find that Sines and Triangle will 'click less' than pulses or saws.
