As a newcomer to Ketron, I just found a very helpful tool for singing and playing from backing tracks.

Say I want to lower the pitch of my SMF to better fit my singing range, but that puts me in an awkward key for playing. By going into Menue/Keyboard control/Pitch-Volume-Trans, I can switch Keyb Only Trans-ON. This allows me to transpose the keyboard to an easier key without affecting the player.

Here again, the manual is ok as far as it goes, but here is a great feature I stumbled on by accident.
