Yamaha sound in and out

[AHBrown]

Good day. I have a major issue with my Mo 8 board. In was playing a bass line and the lower octave's tune was off. In addition, several mintues later, the sound began to go in and out ( like a wawa pedal).

What's going on ? Any suggestion ?

Do a full backup and then do a system reset.

That might fix it.
