- Piano and fretted-string players practicing from sheet music
- Worth noticing
- The score follower handles repeats, first and second endings, D.C. al fine, and bar restarts.
Field notes
The app accepts either acoustic microphone input or USB MIDI and processes the performance on the phone rather than sending it to a server. Its feedback model separates pitch, timing, duration, dynamics, and extra-note errors, then displays those judgments on the score. The homepage identifies piano and fretted strings as measured and supported, while other instrument families remain under development and are not fully tested.
