Here is my personal view on the development
Arrangers/Organs are designed to allow the performer easy set up and operation, with a logical easy to use interface. (If they wanted computer set-ups they would use a computer)
The idea of an Open Arranger/Organ is to give it the capabilities of a computer system, but as far as the user is concerned; the computer is invisible. (Just like a hardware board)
If you’re going for the Workstation/computer market then the Lionstracs approach is fine, but it is not for Arranger/Organ play.
Thumbs up Workstation,
Thumbs down Arranger/Organ
