Well,
It appears that I cannot develop an RPG Arpeggiator/Trancegate at the present time.
I wanted to include not only an arpeggiator that generates notes, but also a trancegate that generates track volume commands but the latter does not have enough resolution at renoise - meaning, I cannot do volume slicing at the sub tick level.
At least judging by the replies I got at this thread
Thats a shame, could have been really nice to have a tool that generates arpeggiated notes and/or trancegate track commands so that you modify them inside renoise, rather than using an external trancegate filter.
