Yes, the web is full of weird clipping boxes...
I've always wanted to stuff lots of these schematics (at least
the most interesting ones) into a rack and use them as individual
modules for VCOs outputs or any external sound sources...

This might be a dumb question, but most of the schemos are built
around a single +9V supply; if they'd be modified to accomodate
the usual +-12V or +-15V of a modular, would the sound effects
remain unchanged ?

Thanks,
JB
