Just a tip that I don't remember being in the manual.
When anything is plugged into the headphone output the metronome is sent to that output only.
I thought my metronome was broken till I realised I'd left my headphones plugged in and unplugged them.
Its a great feature for live use, just wish it had been documented, would have saved me ten minutes of frantic turning the metronome on and off and scrolling through the manual
