Access Virus B/Indigo "Click issue"

[Matt Seil]

Hello again--it's been a LOOOONG time since I posted. 

I've dusted off the studio after taking a good 15-16yr break.  I started
programming with my virus again trying to emulate some basic 303 to get
my legs underneath me. 

I've been chasing this problem all day:  I'm getting an audible "click"
when notes are pressed.  Happens more in the C3+ range but I can get it
to appear up and down the keyboard.  It sounds like when you hit a
sample loop incorrectly.  We know it isn't a sampling problem!

If I put "Env Amount" to 0 it still happens, it's just not quite as
sharp.  Filter 1 seemed make it a little bit better by choosing a value
around 25.  That doesn't seem to matter anymore however. 

I have a feeling, I'm missing something really obvious.  I'd appreciate
any troubleshooting tips!  Important:  Factory presets don't seem to have this issue, so I'm more inclined to think it's me than the synth, despite the long storage.  

Thanks again,
