I did a quick search and didn’t find an an answer. There seems to be a small amount of time that you have to wait until you can hit the main start button after tapping in a tempo on the aux. pedal. I would like to tap 1234 on my aux pedal and then hit the main start on the 1. Am I missing something ?
Just posting here to say I’ve added this issue on my personal list of things to check. I remember quite clearly, there indeed is a slight delay in tap processing at some times. The other place I’ve personally found is starting a song after stopping a previous one in the earlier versions of firmware.
I will certainly look into this to provide some insight.
