Please add a plugin to S1 acts as a arranger keyboard that supports all styles(auto accompaniment, ); ie yamaha, roland, korg and .. . It is most used in Asian countries. get inspiration from Varranger 2. with a cheap price anyone can access to all arranger keyboards in S1. And if you also make android version, any keyboardist would install studio one on a tablet and use a midi keyboard . you will be a big competitor to all roland yamaha and korg arrangers.
