Does this work for you? You send – from a track with Nebula's – to a track with a Nebula reverb instance. Do you experience unstabilities or glitches? I do. I even had blue screens today. I'm sure, it's supposed to work, but which are the MAST settings I may look at? Buffer size in the host (Reaper) is set to 1024 samples, what else is crucial? Thanks!
EDITH: probably a out-of-RAM issue... I just realised, by reading another thread, that the EMT is quite huge, and that I was mixing in Reaper 32bit
