[sdiy] Tape head collage (pretty much not synth DIY, sorry)

[Tim Parkhurst]

Well, perhaps I should clarify. From what I can understand, the waveforms we
normally speak of are a representation of time vs. voltage. They are
basically a graphic representation of a real time audio event. In this
context, a circular / spiral waveform is clearly impossible, unless you can
go backwards in time for part of the cycle ("what value flux capacitor
should I use in my VCO?"). 

Please correct me if I'm wrong, but the waveforms you show on your link are
a representation of voltage X vs. voltage Y. We've all seen patterns like
this, and similar patterns are fairly easy to create with a couple of
oscillators and a dual trace scope. The poster I was referring to was
someone who was talking about a spiral AUDIO waveform which, again if we're
talking about time vs. voltage / real time event, is not possible. I truly
tried to understand the guy, but I really think he was operating under a
basically flawed argument.

My $.02   ;)

By the way, I am continually impressed with your site! Love the tri VCO core
you designed also.

Cheers!
