A friend (in another part of the country) with access to Buchla hardware, sent me a short demo video so that I could hear the wavefolding range on a CO and also how the timbre change with AM as the modulation depth of the modulating oscillator (tuned a 5th higher than the CO) was cranked up – both with and without wavefolding involved.
One of the things that stands out is that the character of the Buchla’s AM has more clangor and growl when the amount of modulation is cranked up than when I try it in Audulus or the demo version of the Arturia Music Easel clone. There is also kind of a beefier low-end. I should probably compare spectrograms to see if anything stands out.
I was wondering if anyone has thoughts about what might contribute to this. I suspect that this is not just an analog vs. digital thing.
Any pointers on where I might look in terms of playing with the math?
