another VCO wave/glitch question

2006-03-16 by c10h14no2i

Hello,
I've tried sending the triangle out of the VCO to a few different wave
shapers. The sine shaper built onto the vco board, the wave
multiplier, and now the blacet miniwave. On all of them I get a
substantial glitch where the wave crosses the 0v point. It shows up
as a spike on the scope, and an audiable buzz. The vco page mentions
that the built on sine shaper will most likely have a glitch. I just
figured that the wave mult. might as well. The MW shouldn't have the
same glitch. Its late, and I haven't gone through the archives to see
if this could be a problem w/ the MW, but I figured I'd post the
problem here to see if anyone had any ideas. The glitch looks/sounds
the same and is the the same spot w/ all wave shapers. Could the VCO
be causing it?

Thanks,
Scott
