As the Kawai K1 MIDI documentation had errors in it and Nils‘ K1v has got some additional MIDI support (Bank Select, Pan, …) I created a document that describes Nils‘ K1v MIDI support in detail.
The document is a Google Doc. Feel free to download as pdf or any other format that is useful for you. Feel free to comment in the document if you found something that is incorrect or missing.
