Yes, Todd’s videos are great. (I guess you missed my remark up-thread about my studying his videos is what is leading me to figure this out – as there are some great timbres that he demonstrates that I haven’t succeeded in coaxing out of WestCat or Rasmus. So, I am trying to figure out how to do that.
I agree about the panel being a place to look, but I think we are looking at it and drawing different conclusions. On the easel, the mod oscillator is color-coded blue. The complex oscillator is coded red. Timbre (wavefolding) is part of that red grouping. To me, that implies (not definitively, though) that timbre is integral to the CO and that it is the CO’s output stage.
I infer from the front panel that the signal flow is something like below.
(MODULATING OSCILLATOR) modulates
(COMPLEX OSCILLATOR–wavefolding integrated internally and applied to the complex oscillator output)
as opposed to
(MODULATING OSCILLATOR) MODULATES (CO’s pre-timbre waveform) -> wavefolder (Timbre)
By the way, the sounds that I am trying to coax out of Audulus include the type of timbres heard here:
As I have been playing with some waveshaping/folding software, I am getting the sense (I could be wrong) that what can sound like subtle differences in waveshaping algos can have a big impact on the final sound when it is combined with AM or FM. It seems like Buchla spent a lot of time experimenting with designs.
