In short it won't record, or playback a sequence, the metronome isn't working either...??

I'm new to this & was recording in a chord, I went to save it, but by mistake the record button was still on, & I pressed MEMORY & M8 instead of the right buttons to save, I was playing on 1/4 notes TEMPO too! & that's it......

Now it will not record, play back a sequence, & the metronome doesn't work...!?!

All the buttons are the same as before (as in on the step sequencer), but now when I press the record button, & the play button too, or just record, & tap a few notes, nothing happens in terms of recording & playing back the recording...

& Like I siad, the metronome won't work either!!! I turn it on & off & there's no sound....

Why...???

I've even set it back to factory settings to rectify the problem, but it's still the same, even again, when I have all the same settings on the step sequencer...!?!
