I calculated it once more:
Let us have a look at what happen if we play e.g. variation=4, chord=Maj. That's what Roland call a Division or Pattern. A Pattern can contain up to 8 Midi sequences, simultaneous played on 8 different tracks.
Each Midi sequence contains Bank Selects and a program change. So every Pattern can play 8 different tones. There are up to 54 Pattern, so up to 432 is the number of tones within one style if no further program changes occour. But this is far, far away from the reality. So this discussion is useless, I think. Important is the great flexibility of Rolands Style- Composer, Converter.
