[sdiy] vcos

[Scott]

I also have a VCO which is way more buzzy than my other few, but I can certainly see the glitch in a scope.  Same VCO has wave shapers, and that glitch carries through to the sine and triangle.  A short spike on the rising edge.  
Maybe I'll revisit that issue.  It's been a few years since I worried about it.  I may have learned a thing or two in that time.

Hi Ian,

I'll try to make some audio clips this weekend.

Unfortunately the only recording device I have in the studio is Minidisc, so 
I'm not certain if the difference will be audible with the compression 
(essentially an MP3).    My computer is two floors away... Man, I need a 
laptop!

The difference is pretty subtle - more "buzzy-ness" on the saw, etc... which 
I assume is a difference in harmonic content.    For reference, I have a 
3340VCO and a trio of EFM VCO4D (which was a Moog Sonic Six clone, IIRC)

Dave
