The option to render to disk in mono would be more than useful for me. I like to synthesize for instance drum sounds in renoise but all my results need to go somewhere else afterwards to get them files (for instance kicks etc) really in mono. I like to take care of cpu and don’t waste any space, that’s one reason why I’d like to have files dedicated to be in mono, not in double mono or pseudo stereo.
+1 for mono rendering. So useful for bouncing stems.
