MOTM

http://www.orange-records.com/test.wav  (500k)

this is a MOTM, oscillator into filter into vca, with the vca CV controlled
by an envelope.

hear the clicking?

Is this normal?

Attack is not set to 0 (ie there is a bit of attack), if i turn the attack
up, it still clicks even when i have an obvious ramping attack.  if i turn
the filter cutoff down, it still happens. I have other samples with varyoing
levels of attack/filter, all the same.

It's not the VCF, it's not the sequencer, and it's not the envelope (tried
all different ones), and no, it's not my amp/mixer/computer, etc.   If I use
a VCA from another synth, it doesn't happen.  I'm told the VCA is
"performing within spec", but I can't get it to make a bass note without a
major click.  Am I the only one who has this problem?  Am I doomed to not
use my MOTM for bass notes?

Thoughts?

That sounds like the CV rejection trimmer needs adjustment.

Hmmmm. I'm still at work and don't have the 190 manual handy, so I 
don't know the cv rejection spec, but there will always be some 
bleedthrough. I used to think that the 110 was quite bad in that 
regard, and that my 190s have been much much better. I've never had 
any popping like you describe unless I use the very fastest attacks 
on the 800, and they disappear if I back off a few milliseconds.

I'm just fishing here, but are all the modules on the same power 
supply? Also does VCA1 vs VCA2 make a difference? Lin vs Exp modes?
