Besides samples, wavetable, fm, granular, whatnot, I want to be able to use any VSTi as “oscillator” and any VSTfx as insert fx for busses.
Use case: use multiple instances of a given VST2 i with states synchronized as VST3 Note Expression targets round robin style, to play a VST2 “sound” with NE.
In General: use HALion as Central VST Sound Station/Playground.
