Hi guys!

I'm drawing loose sketches on a three ASM VCO board. To reduce size I hope
to make use of as many SMDs as possible.

Are there any specific "demands" on that (or any) VCO board design? A part
from the lin-log components beeing close/glued together. Will I get any
unwanted soft sync effects from traces going parallell to long? Or are the
traces on a PCB the size of a ASM VCO simply to short to have any effects
of that kind at all? Or does unwanted sync things has more to do with
porely regultated/filtered power than "badly" placed components .

This will be a real compact design since I aim to build a four voice, three
oscillator module.  I hope to make room for "global" CV ins as well voice
specific CVs . I have yet no idea on how to patch this unit together with
other polyphonic modules. Maybe matrix switch chips or five pole DIN
suggested on the list before.

If I were to give board a name it samply has to be  'a ASM VCO SMD PCB',
which I find rather fun...
