hope this is no old news.
will cost you some bucks though ~(€35 or €55)
if you use thalamus you can get energyXT or console fully working in renoise, meaning you get a modular routing environment with perfect multitimbral vsti support inside renoise (or any other host) + some other nice goodies.
i have tried out with energyXT demo and it seems to work fine. automation also worked. and you don’t have to scramble all notes into one track, you can use as much as 64 tracks for sequencing.
however, i haven’t really tried out very deeply since i don’t own it, so who knows, the devil may hide in the detail…
just in case you’re in desperate need of multi-out or modular routing.
