I trained a 125M model to autocomplete piano on-device▲598
I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Pianolyze▲149
Hey HN, I'm a pianist who's always been obsessed with understanding how great players think through harmony. What voicings are they using? How do they voice lead through changes? What's actually happening under their hands? Back in 2022, I built Harmonic Analyzer (https://www.youtube.com/watch?v=iNgSgvUmiOs) – a Mac app that used ML to transcribe polyphonic piano recordings. It got some traction, but I never quite finished it. Requiring users to download a Mac app felt like unnecessary friction, and I didn’t want to limit distribution to Mac users. I just shipped Pianolyze…
