When I select "keyboard and style" nothing seems to happen. There's no deeper menu page that opens up.
Q: If I do a factory reset for only the "System set up" and the "midi setup" would I also lose the hundreds of registrations I have set up on the kb?
Save all setups etc, to a USB drive first then you can
reload them easily. have you called TC helicon to see what they say?
