When I look at the advertising of BIAB it says RealDrums and RealDrums ... I suppose the next feature is "RealTime"

Typing in chords is not RealTime. RealTime is fading in Bass/ Drums/ Orchestral and controlling the BPM and controlling key changes from the Midi keyboard.

Or maybe you start from the Typing In Chords and move over to improv key changes mid song.

Yamaha/ Korg/ Roland may reserve rights to their proprietary software ... locking it to hardware ... but this has to be on the horizon. Is it ?

Thanks again.
