Is there some sort of audio crossover native to Renoise. I want to experiment with splitting up the highs mids and lows on a track and send them to separate buses. And if it’s not native to Renoise is there anything else people would recommend?
Renoise 2.7 has the Multiband Send which does exactly what you want:
