Thank you for your reply. In both midi and audio, the issue is the change in volume level, both left hand and right hand, (chord rhythm backing and melody line). This only occurs when the record button is used, AND ONLY on the first , button #1, of the registration bank. Both volumes drop back at last 50%, but then moving to the next registration, all comes through as set, then if I go back to registration 1, it too sounds as it should, and I can vary as much as I want to between registrations, and all plays as set. All this I checked, before recording. The recording is good. The problem of reduced volume is only when the recording button is activated, midi or audio, on button #1. If I start on any other reg. button, all is normal, AND THEN if I then go to reg. button one, all comes through normal. Basically I can’t start recording using reg.#1. Apart from that all operates fine. I hope I have explained this well, and look forward to any assistance. Many thanks to you, Ray,
