Import Ableton Live Sets!
eg Patterning and Blocs Wave export their Arrangements as Ableton Live Sets.
So there must be a description how to implement that.
These Sets should be importable vor Groove Agent into Cubase. And as mini Groover within Cubasis: Predefined Drumstation like the drumstations within Cubasis with an additional Tab to trigger them via Midi-Patterns (into which the Live-Sets should be transformed). Complex, but easy, and: Would make Cubasis the greatest IOS-DAW ever!!!
