I’ve come up against a brick wall with Renoise… The 255 instrument limit.
To work around that I guess I could run 2 instances of Renoise - is it possible to sync 2 instances via Rewire?
I’ve done that with Renoise and Live/Reaper before but not with 2xRenoise
Have you already merged as many one shot samples as possible? And/or if you have instruments that are just duplicated tracks you can merge them into one instrument as well. Obviously the latter won’t work if you have different DSP chains for them.
If you’re not using 100% of the instruments and some of them are just resamples or things you resampled, save as into a new song (just to back them up in case you need to go back) and do the delete unused instruments thing.
It depends on what is in it.
256 Midi out instruments are loaded in a jiffy.
256 instances of Kontakt or Symphonic Orchestra with a large sound-pack, might take a little longer
A Vst host that can bounce down plugins to soundfonts and works as a VSTi itself.
I guess if some of your synths only play in unison, they could be loaded in a Chainer VSTi, using only 1 renoise instrument slot.
