That patch is gorgeous. I was able to reproduce it, and then I substituted VCO Lab for the FM Op, and it still sounded great. I had to run the feedback through a VCA before going to the phase modulation so I could get the dynamic feedback level. I was able to pretty much match the sound of the Bogaudio FM Op.
Where HQ really shines is when used to establish harmonic frequencies to be used for all manner of modulation:
- Phase modulation
- Linear through zero frequency modulation
- Amplitude modulation
- Ring modulation
And now we can add coordinate system transformation. I think maybe the technique needs a good name!
I think most people think ring modulation is inherently inharmonic and metallic. But just like all the other modulation forms, it can sound very sweet when using integral ratios for the modulator. I made a demo using HQ and Recurse. Ring modulation can also sound great when applied iteratively.
