Hi Rookie,

In worst case scenario you need then 3 of those "kind of modules/functions", one for each notes, 3 notes, 3 modules...

Did you had a look into Sinfonion from ACL if that can helps you out? Check their manual for this module especially the chord section and the sequencer section, with a combination of both of these (chords & sequencer) you might get close, but perhaps not exactly what you need.

Good luck with the search and if you find the answer please let us know, it's quite interesting :-)

Kind regards, Garfield.
