Hello everyone! Just getting into VCV here and having a lot of fun so far Got a question about a particular thing I wanna achieve.
Let’s say I have a VCO and I want to change the output frequency by harmonic-series ratios meaning double the frequency, then triple, then quadruple etc etc.
I have worked out a number of ways to do that discretely, meaning insta-hop from one frequency to the next, but now I’m trying to find a way to smoothly crossfade from one frequency the next, in sequence.
This obviously requires a poly VCO, and I’ve found a way to process v/oct CV such that the VCO gets the fundamental frequency on the first channel then the second, third, fourth etc harmonic on suebsequent channels.
(In related news, with this setup any poly VCO becomes an additive synth which is pretty sick in its own right, but not what I was going for hihi).
So now what I’d love to do is find a way to sequentally crossfade between poly channels. So like, start with the first channel at full amplitude and all others at zero, then crossfade from the first to the second, then when the first reaches zero and second reaches full, crossfade from the second to the third, then third to fourth etc etc.
Ideally this sequential crossfade would map to a single voltage in the end. So you could turn one dial to smoothly transition up the overtone series.
So, any ideas on good ways to achieve this?
(P.S. a very reasonable suggestion is to simply use a wavetable VCO and load a harmonic-series WT. I do that sometimes, but I’d love to be able to do this arbitrarily with any VCO)
