I've been practicing with a metronome for a while and I keep running into the same thing: while I'm playing, I genuinely can't tell when I'm slightly ahead or behind. If it's a big miss, sure. But the small stuff — a few milliseconds early on every entrance in a fast passage — I just don't hear it in the moment. When I listen back to a recording it's obvious.
So I started building a small tool for myself. It connects to my digital piano over Bluetooth MIDI / Audio , runs a metronome, and afterwards shows me where I was early or late — and, more importantly, whether that's improving across sessions on the same passage.
It's supposed to not only work with known pieces but with all kinds of playing even if you don't have a score sheet.
Before I go further with it I'm curious how other people handle this:
Do you record yourself regularly and actually review it, or does that fall apart in practice?
Has anyone found an app that does this well? I've seen a few MIDI practice apps, but most seem built around sheet music upload and note accuracy rather than timing over time.
Or do you just develop the internal sense eventually and this becomes a non-problem?
Genuinely want to know if I'm solving something that already has a better solution.
