Roland released the VE-GSPRO for the MC80 with 32 parts multi timbral (16 midi channels on 2 midi out ports).
Is it possible to use on A90/70 the full capability of the expansion board with 32 parts?
A90/70 seems to have the possibility to edit only 4 parts by turn (4 internal zones)up to 16 parts (one for each midi channel).
