Without going modular, what are the hardware synth options with built in wave folding or other cool modulation things like some of the nice Max for Live devices or intellijel metropolis (Edit: Atlantis… which I thought has a wavefolder, but it doesn’t, just some brilliant modulation options)?
Wavefolding is on several semi-modulars, including Taiga, West Pest, and Arturia’s minibrutes (as “metallizer”). Mavis has it too but it’s not directly cv-controllable (I modded mine for it, but in general Mavis, with no midi, is more of a modular affair).
Edit: O-Coast, too. Its multiplier circuit is like a folder but with more going on under the hood, and its modulation possibilities for it are excellent.
I have the Argon8M specifically for its ability to being able to wavefold after filter and filter distortion
(I chose Argon over Cobalt since the Cobalt8M does not have filter distortion)
All the recent Pittsburgh Modular have wave folders, west pest is the cheapest, for a little more you can get a used microvolt or a tiaga and get way more. The new voltage lab is expensive but so so worth it if you can afford it.
