just few minutes ago i accidently pressed red knob on a tempo screen while adjusting metronome pitch , what happened is… metronome started to behave like “locked”.
i mean each time i press metronome knob… it locks for couple of secconds in adjusted point. is it a bug or maybe is it some helpfull feature i cant understand ? 
if it’s a bug… then be carefull on stage cause as i find… there is no other way to turn off a metronome except just waiting haha
