What is KeyStage?

KeyStage is a Master Instrument Controller iOS (iPad) App through which you can control and play
both keyboard internal sound engines and iOS virtual instruments. Check out the App’s description
at the App Store https://apps.apple.com/gb/app/keystage/id1406132634

How can the Roland V-Combo VR keyboards work in conjunction with KeyStage?

There are 3 areas where Roland VRs and KeyStage can work together:

1. Playing sounds in the Roland VR’s GM2 sound engine

2. Translating the Sysex output of the VR’s hard organ controls (drawbars etc) into the Change
Control’ (CC) numbers s required to control iOS virtual organs

3. Playing other iOS virtual instruments. And there are thousands out there! And these can be split
and layered with sounds in the Roland VR’s GM2 sound engine if required
