Sorry, one last thing. I’ve just tried render to a single file, (“whole montage” type render) in a session with many UAD clip plugins in Reap*r, and found it doesn’t even use 100% dsp for that.
It uses minimal DSP incrementally (current render clip dsp only) just like the “regions/tracks” type render. So maybe that’s dynamic plugin switching being used (?)
Wavelab uses “all uad plugins in montage” uad dsp for a “whole montage single file” render.
