I'm working on Trebella [0], a tool to help classical music students structure their practice sessions more effectively. I tried to build something similar ~10 years ago in the form of a more interactive music game, but felt like it wasn't actually that helpful for intermediate and advanced students. So this time I'm doing it in collaboration with actual music teachers and building a tool that actually helps me learn. I'd say 90% of my flute practice is done using it at this point, and I'm in the process of taking on the first arms length users in a closed beta. Please shoot me an email if you are interested in any way!
Great question. I’m using MOSS-audio for that which feels good (and is fast/small enough) but not sufficient to give useful feedback out of the box. I’m working on fine tuning it on a bunch of masterclasses on YouTube and recordings sourced/labeled by my friends. That’s really the blocker for me to feel this is ready for prime time. But the rest of the app already helping me structure my practice.
