[sdiy] Chaotic/lo-fi patching techniques

[Jim Panci]

It seems one could take the bed of nails and the worm ideas and
combine them with a slightly less sadistic approach. The performer
could lie on the bed of nails himself as the ultimate expression of
randomness meets dedication to art. The more blood that flows the
better the contacts, hence, the more intense the sound (presuming
correct design, of course). The truly dedicated will not mess around
with wimpy solid state synths but will go straight to custom modified
tube gear. Gives new meaning to the phrases "wretch machine" and
"performance pressure"!

Alternately, one could just employ a voltage controlled power supply.
Control of output voltage and current limit should be easy. You could
control the plus and minus rails separately for asymmetric sorts of
effects. For a real challenge you could create a voltage controlled
capacitor out of between 8 to 12 relays, a similar number of caps with
value approx 2^n * smallest cap, and a suitable A to D chip to give
you voltage controllable filtering.
