Tremulus smooth ?s

[keninverse]

so everthing seems to work and except the smooth knob does not do a lot. Probably because there's something wrong with the LFO. I can see a notable lag on my CRO when the LFO voltage reaches it's max and min. I figured it's gotta be a cap that's not charging/discharging correctly. so I scoped around and the 10nF feedback cap shows glitches at the same instant where I can see the voltage lag. When LFO voltage gets high it gliches versa for the low voltage. You guys think it may be this cap? should I put something smaller there? Maybe the VTL5c2 is just waayy too slow.  I'm using the tonepad layout...

It's unusual for a cap to screw up like that. I'd put a cap in at 1/10 of the value, for a start.

I'll try that.
I was also noticing on the VTLC2 datasheet that these are pretty "slow" compared to some of their cousins.  could this be an issue?

finished the box.  The smaller caps helps a bit but the glitch is still there.  I think there's more of an issue with decoupling the power rails of the IC.  I'll check this out and report back.
