Bottom line is …renoise never had the ability to output 'renoise instruments’to specified tracks …no matter which track you inserted an instrument , it also functioned as an audio bus/track …so we can spread the same instrument across multiple tracks …
You can still work with this way UNLESS you have instrument/effects tied …there is no possibility to choose an output , the output = the track where you put your note data and there can only be one …multiple tracks results in cutting of the audiostream etc…
Useless for creating rhytms ( with effects tied in instruments )
