@Akiz: thanks! … I simply forgot about putting it on the tool page somehow, will do within the next days.
About using note columns instead of tracks for output: I had that option planned from the beginning, but never implemented it.
Personally, i don’t like using note columns for drum sounds, even with renoise 3 fx chain instruments i rather copy the instrument and use multiple tracks.
I’ll keep it in mind for the next version, but can’t promise anything (anytime soon).
