Tsumugi · Guitar v1.5: Edit notes, instrumentation and performance details.
SwiftF0 0.2.0 uses its official pitch tracking and note segmentation for monophonic recordings. Outputs MIDI, frame-level pitch CSV and a plot.
SwiftF0 0.3.0 tracks pitch in monophonic recordings and exports MIDI, frame-level pitch CSV and charts.
Spotify Basic Pitch transcribes polyphonic performances from nearly any instrument, including voice, into MIDI and optional note-event CSV with pitch bends. It works best on one instrument at a time.
GAPS converts clean or separated solo guitar into note events and MIDI, without string positions, frets, continuous F0 or Pitch Bend. Adjust MIDI velocity by comparing with the original recording.
Guitar-FL converts guitar solos from the François Leduc data domain into discrete note events and MIDI; FL does not mean frame-level. It does not output continuous F0 or Pitch Bend.
FiloSax targets monophonic jazz saxophone solos and exports discrete pitch, onset, and offset events as MIDI. It does not output continuous pitch, slide, or vibrato tracks.
FiloBass targets monophonic jazz double bass (upright bass), not general or electric bass. Use a clean or separated stem; kick and low-frequency bleed can create false notes.
VioPTT outputs violin note events and one of four technique labels—détaché, flageolet, spiccato, pizzicato—or none. MIDI velocity is fixed, not measured performance dynamics.
STRAdi Online targets clean solo violin with fully causal inference and no future context. It exports discrete MIDI plus onset, offset and pitch CSV; the public repository does not ship a score-following system.
STRAdi Offline is the matched non-causal, full-context reference route. It exports the same discrete MIDI and onset, offset and pitch CSV; it is not a published score-following system either.
Convert guitar recordings to MIDI with the GAPS paper checkpoint trained for 12200 iterations.
Tsumugi · Bass v2: Edit notes, instrumentation and performance details.
Tsumugi · Other v1.5: Edit notes, instrumentation and performance details.

Official technical guide - 2026
Convert isolated instrument, vocal or drum tracks to MIDI using the matching official model. Vocal harmony also supports the v1.6 checkpoint. Instrument label refinement remains experimental.
Includes public test results for models used here and elsewhere. The complete source table is shown by default; conditions and metrics can also be selected for comparison. Scores from different test conditions are not directly comparable.
Only records with verified public inference implementations and matching weights are shown; algorithms requiring no weights are also eligible. Closed services, unreleased weights and unmatched experiment versions are excluded. This is not an all-model leaderboard.
Public weights do not establish a fully open-source license. Expand the data for declared weight licenses and access conditions. Undeclared licenses are marked separately.
The selected model has no verified matching public result and has not been ranked.
Choose a dataset to view all metrics for each model. Rows follow the official rank or selected metric. Bold marks each column’s best comparable value, including ties. Different evaluation protocols are ranked separately; missing scores are shown as -.

SwiftF0 0.2.0 uses the 2026-09-19 snapshot of the author's pitch-benchmark: 10 corpora, 8 scored conditions and 50 cents tolerance. This is pitch F1; the difference from RMVPE is statistically undetermined. Asymmetric 95% CIs are retained. REAPER is unranked due to incomplete results; the older 0.1.x paper does not score 0.2.0.
