Sopman52

Hi, Spot on! Though why the effect only takes place after a short while is beyond me. Anyway, a huge thankyou for taking the time to help, it is greatly appreciated.

I'm a newcomer to such a sophisticated piece of kit as the 560m, so its quite possible I am missing something. My problem is: after being turned on for 5 minutes the upper 1 tone changes sound from grand piano to a synth tone. The icon still displays grand piano. The only way to get it back is to go to the main menu>mixer> and then de-select Part1, Part2 and Part3. Powering it on and off does not restore and equally a factory reset is no help. I would appreciate some help.
