Dated post but I agree a standalone metronome option would be golden for this app. I'm new to Stage Traxx but I play live a ton, have my IEMs connected, and songs tee'd up, BTs to FOH, then...
BAM! someone aka band member or audience / karaoke i.e. come up and sing request - will inevitably call out a song not on my list - and i'll have no metronome for it.
I could bring a seperate device and mix it in and all that, but what's the point if I already have ST3/iPad all connected?
O.P. has a great suggestion here - a STANDALONE METRONOME in the app would be SUPER useful - can't be difficult to incorporate into ST3, right?
