I can't see it would be very playable on the Orba's. I have experimented with manipulating samples so they reach their peak volume at different times which can give a strummed sort of effect, and unintentionally the Preset Creator make chords that can have high notes dying out while the lower notes continue - sometimes a long time - that can sound rather cool.

Why did Orba 2 never get an arpeggio mode? Clearly it could have (even if it had to be enabled via the Connect App)
