I bought a BOSS ME 80 Multi FX pedal last year and have been learning how to set up the delay for home use and recording with it. Since the pedal has a small screen that displays the milliseconds of the delay, I take out my phone, tap the beat of the song on my metronome app to get the bpm, divide that by 60 to get the quarter note ms, multiply it by 750 if I want the dotted eighth note or divide it by 2 if I just want the regular eighth note. This method has worked great when I'm at home and recording because I can follow the metronome and get the exact BPM of the song. I was jamming with a friend on Friday and it was a different story. I found myself unable to figure the BPM of what we were jamming to on the fly and the tap tempo option on the Boss Me 80 pedal isn't very accurate when registering taps. So, tap tempo aside, how do you set up your delay in a live setting where things get unpredictable? I would like to be able to set my delay without having to rely on my calculator or the little screen that displays the milliseconds.
