If a synth (digital) can use an oscillator as a modulation source this doesn't necessarily mean the modulation actually performs at audio rate. This was actually discussed a couple of pages back in this exact thread.BONES wrote: ↑Fri Jan 15, 2021 3:38 amOf course it runs at audio rate, it's one oscillator modulating the other. It doesn't kill your CPU at all because your oscillators are already running at audio rate.Also, osc cross-modulation should run at audio rate to sound good which may require quite a some CPU.
It's the modulation accuracy what taxes the CPU (try different accuracy options in Dune3, iirc you have it).
As for the rest of you post, you asked me why I need wavetable synths and I answered that question. You may have different thoughts on wavetables, that's fine, whatever works for you. Yes, you can approximate the sound of certain wavetables using 2-osc FM or sync, likely because these have been made with FM or sync. There is no specific sound inherent to all wavetables because they may be prepared in very different ways and have very different sonic qualities.
Actually yes, and I like the Bazille's sound very much too.
But making a meaningful patch in Spire for me is 500 times easier than in Bazille
