Voltage Controlled Waveshape (was animation (was Re: [sdiy] Imperfect VCO)

[mark verbos]

right, but Don's are simple crossfades between 2 things, or on the 259 
there are several CV ins to control several parameters, HOWEVER, what I 
am refering to is sweeping accross several more or less unrelated things 
with one voltage. That can be done with the interpolating scanner, by 
putting whatever signals into the inputs.... however in this case it is 
all waves from the same VCO that it's hardwired to.

My guess, and it is only a guess, is that the Serge NTO was an attempt 
to have the possibilties of the Buchla 258 plus something more in it's 
waveshaper. That's why they have the sine between the saw and square. 
Then you can set it up to sweep from sine to either, so it can be set up 
as either of the 2 oscillators in a Buchla 258. Which had already proven 
to be a valuable resource. You'd have to be really careful with the 
voltage so you don't "oversweep " though.

I don't know about the Moog's transistions though. Was Gene suggesting 
that they don't actually crossfade, but "morph" from wave to wave? The 
Buchla 258 crossfades between a sine and the saw or square. I don't 
really know about the Serge. I think the MicroMoog also crossfades.

anyone?
