Thread: I don't speak drone
I think one possibility not discussed is mixing.
Think of an oscillator with 4 simultaneous waveform outputs. Connect all four audio outputs into a VCA module that can mix like an Intellijel quad VCA. Then connect four modulation sources into the CV inputs... maybe a quad LFO like the Xaoc Batumi and set the Batumi to really slow rates. Of course you don't have to mix just one oscillator... or you could mix between effects or even mix CV sources instead of audio.
If you combine mixing with filter modulation, etc. the sky is the limit.
