One last thing. I don't like fumbling for my phone when I just want a metronome pulse so I bought one of those old school ones like this. Simple, quick, and no BS.
OK boss, I'll try your suggestion. I did buy an old school metronome like yours. The bummer is that the chime for the '1' beat isn't loud enough and there's no way to turn it up.
I'll give that app a try too. I tried the speed changer on YouTube but the sound was so bad I quit doing that.
You're the man!
Edit to add.. I have a Vox that I use with headphones. I'll use input and put metronome app through there and see if that works.
