OPZ Sample Mode W/Metronome + W/OUT Holding Rec Button

Hey all

Wondering if there is a way to either A) monitor back the metronome through headphones whilst recording samples in sample mode, via whatever input mode or B) ideally be able to monitor the whole loop playing in the background whilst sampling.

I sometimes want to play a short live piano chord run down from my baby upright piano or a little drum fill on my acoustic drum kit (to fit in those lo-fi jazz hop tracks ;-p ) but have no reference for the timing/pitch to do these…

Plus these things would only be possible if I can do it withOUT holding the Rec button down when in sample mode. Is there a way to just press it in sample mode and it stays recording over the whole 6/12 seconds?

Cheers

Myles
