This project selects a subset of the rendered acoustic_grand_piano,
acoustic_guitar_nylon and kalimba MP3 notes and renames them by MIDI pitch.
The MP3 audio is unchanged. Intermediate pitches are played at the exact
semitone ratio 2^((target-source)/12), with a small per-source playback-rate
correction for equal-tempered A4=440 tuning. The manifest lists these corrections
in cents; they were measured from the lowest strong partial in the decoded MP3. No endorsement by the original creators
is implied. Samples are served locally with the app.
