The record is our own.\n\n## Saved content\nAnswer first: a seven-step agent checklist for editing a MIDI file with mido without breaking its timing, framed as steps to try and record: keep the original and edit a copy; read ticks_per_beat and every set_tempo before converting times; keep delta times integer ticks; edit through copies and inside the ranges; keep the file type consistent with the track count; check end_of_track and track lengths after editing; and compare the playback length before and after. Then a concept, documented meaning, helper or attribute and where table, with the Basic Pitch record used only through its revision 1 pins for the MIDI it outputs and the tools pointer record only through its mido row. Licence parts reported as the files state them. Curator analysis, untested; nothing installed, run, read or written.\n{\n  \"text\": \"## Answer: a seven-step agent checklist for editing a MIDI file without breaking its timing\\n\\n- Curator's analysis, untested: the mido docs describe messages and files, not an editing procedure, so the seven steps arrange what they state and the checks are ours. Nothing was installed or run, no MIDI file was read, edited or written and nothing was played. Live ports and backends are not described. Step 1, keep the original and edit a copy. The MIDI files page says the entire file is read into memory, so tracks and messages can be modified and saved back with save. If the MIDI came from audio, our Basic Pitch record, revision 1, reports a MIDI file out complete with pitch bends and an allowed note range set by a minimum and maximum frequency in Hz; record the tool and range.\\n- Step 2, read ticks_per_beat and every set_tempo before converting times. The docs say a tick is the smallest unit of time and stays fixed through the song, each quarter note is divided into ticks, and the resolution is stored as ticks_per_beat; typical values range from 96 to 480. Tempo is microseconds per quarter note with a default of 500000 (range 0 to 16777215), which at 4/4 corresponds to 120 beats per minute and, because a beat follows the time signature denominator, 60 in 2/2. Both set_tempo and time_signature can change during a song; the default time signature is 4/4 since 1.2.9. Curator arithmetic from the docs numbers: 500000 divided by 480 is about 1041.7 microseconds per tick.\\n- Step 3, keep delta times integer ticks. Inside a track the time attribute is delta time in ticks and has to be an integer (a non-negative integer, per the messages page); in messages from play() it is delta time in seconds, and iterating a MidiFile gives seconds since the last message. tick2second and second2tick convert; integer rounding might be necessary, and bpm2tempo and tempo2bpm convert tempo, the latter possibly returning a float. All messages are tagged with delta time in ticks.\\n- Step 4, edit through copies and inside the ranges. The intro page says channels are numbered 0 to 15, type and value checks run when parameters are passed or attributes assigned, and attributes are settable though copy() is better; the messages page says Mido always makes a copy. The message types page gives note a range of 0 to 127 and the about MIDI page says data bytes are 7 bits, so a transposition needs its note range checked (our inference), and the key_signature value comes from a fixed list. Unknown meta messages are saved back exactly as read.\\n- Step 5, keep the file type consistent with the track count. The docs list type 0 (single track), type 1 (synchronous, all tracks start together) and type 2 (asynchronous). Type 0 has exactly one track, and saving a file with none or more than one raises ValueError. Splitting parts into tracks therefore points to type 1, and merging into one track to type 0 (our inference).\\n- Step 6, check end_of_track and track lengths after editing. end_of_track is an empty meta message marking the end of a track; if a track lacks one at the end, one is written anyway on save. A track is a list of messages with delta times, so its length in ticks is the sum of those times (our inference); compare it with the original.\\n- Step 7, compare the playback length before and after. The length property gives total playback time in seconds, supported only for types 0 and 1; a type 2 file raises ValueError. Log length, ticks_per_beat, the tempo changes and the track count for the original and the copy, and note any difference (our inference, untested).\\n\\n## Concept, documented meaning, helper or attribute, and where\\n\\n| Concept | Documented meaning | Helper or attribute | Where |\\n| --- | --- | --- | --- |\\n| Message | A Python object, checked on creation and assignment, copied rather than modified. | Message, copy() | intro;

Then a choice, docs statement, setting and where table, with the Basic Pitch record used only through its revision 1 pins for the MIDI it outputs. Curator analysis, untested; nothing installed, run, tokenized or trained.\n{\n  \"text\": \"## Answer: a seven-step agent checklist for preparing a folder of MIDI files for a symbolic music model\\n\\n- Curator's analysis, untested: the docs describe a library, not a preparation procedure, so the seven steps arrange what they state and the round-trip check and record-keeping are ours. Nothing was installed or run, no file was tokenized, no tokenizer was trained and nothing was downloaded. Step 1, say where the MIDI came from. The music formats page says MidiTok supports MIDI and abc files. If a file came from audio, our Basic Pitch record, revision 1, reports that its README gives a MIDI file out, complete with pitch bends, sets the allowed note range with a minimum and maximum frequency in Hz (events outside are excluded) and has a flag that also saves note events as a CSV file. Record the tool, flags and range.\\n- Step 2, choose and record a tokenization. The README lists eleven: REMI, REMI+, MIDI-Like, TSD, BEAT, Structured, CPWord, Octuple, MuMIDI, MMM and PerTok. The tokenizations page describes MIDI-Like with TimeShift and NoteOff tokens, TSD like MIDI-Like with Duration tokens, CP Word with tokens of the same family grouped, Octuple with bar and position embeddings, REMI+ as REMI with use_programs, one_token_stream_for_programs and use_time_signatures enabled, and BEAT with four steps per beat overriding beat_res and no support for pedals, control changes, pitch bends or chords. The workflow page says the first three preprocessing and parsing steps are common and each tokenizer handles the time tokens. If the MIDI carries pitch bends, how each tokenization treats them needs checking (our inference).\\n- Step 3, record the time handling and special-token configuration. The configuration page says MidiTok resamples the time division to the resolution set by beat_res, which determines the time tokens, and warns that time signatures with rests in CPWord, and time signatures in Octuple, might result in time alterations. Special tokens default to PAD, BOS, EOS and MASK. The page writes BOS as SOS_None while the README example indexes BOS_None; both are recorded and not reconciled. For an already preprocessed score the page says to pass no_preprocess_score as True.\\n- Step 4, save the tokenizer with the data. The workflow page says a tokenizer can be saved and loaded with its configuration and vocabulary. The README example calls save, the PyTorch page example calls save_params, and the Hub page says save_pretrained is equivalent to save_params; the call names are not reconciled here. The Hub page also says from_pretrained loads from the hub or a local file. Nothing was pushed.\\n- Step 5, train a tokenizer only on data you can name, and record its vocabulary size. The README says tokenizers can be trained with BPE, Unigram and WordPiece. The train page says training populates the vocabulary with tokens for successions of basic tokens, that all tokenizers can be trained except those with embedding pooling, that Unigram is not deterministic, with defaults of a 0.75 shrinking factor and 2 sub-iterations, and that WordPiece is to be used exclusively while splitting ids per bars or beats. Ids can be split per bar or beat so learned tokens do not span them. After training, the workflow page says a new vocabulary is built from pairs of basic tokens. Datasets any page names are pointers only here.\\n- Step 6, split long files the way the PyTorch page describes.

the library was released with a paper at ICASSP 2022 (A Lightweight Instrument-Agnostic Model for Polyphonic Note Transcription and Multipitch Estimation, named only).\\n- The README says the tool has been improved beyond what the paper presented and asks that academic users who use its output cite the version of the code used.\\n- Compatible environments are macOS, Windows and Ubuntu with Python 3.7 to 3.11, and for Mac M1 hardware only Python 3.10 is supported.\\n\\n## Options table: what the README documents\\n\\n| Option | What the README says it does | Default if stated | Source section |\\n| --- | --- | --- | --- |\\n| basic-pitch OUTPUT-DIR INPUT-AUDIO | Saves a MIDI file transcription of the audio to the output directory | MIDI file is the base output; other formats need a flag | Command Line Tool |\\n| Several input paths | Processes more than one audio file in one command | Not stated | Command Line Tool |\\n| --sonify-midi | Also saves a .wav rendering of the MIDI file | Off unless the flag is added | Command Line Tool |\\n| --save-model-outputs | Also saves raw model outputs as an NPZ file | Off unless the flag is added | Command Line Tool |\\n| --save-note-events | Also saves the predicted note events as a CSV file | Off unless the flag is added | Command Line Tool |\\n| --model-serialization | Switches to a non-default model type, for example CoreML instead of TF | Load order TensorFlow, CoreML, TensorFlowLite, ONNX | Command Line Tool, Model Runtime |\\n| basic-pitch --help | Pointed to for more parameter control; its output was not read | Not applicable | Command Line Tool |\\n| predict() | Takes an input audio path and returns model output, MIDI data and note events | Not stated | Programmatic |\\n| Minimum and maximum frequency | Floats in Hz that set the allowed note range; events outside it are excluded | No default stated | Programmatic |\\n| predict() in a loop | Load the model once and pass the model object to avoid repeated loading | Not stated | Programmatic |\\n| predict_and_save() | Orchestrates saving: booleans for the MIDI file, a WAV rendering, raw model outputs and note-event CSV, plus a local model path | Not stated | Programmatic |\\n| Model runtime | TensorFlow, CoreML, TensorFlowLite or ONNX builds; which is installed depends on the operating system and Python version | CoreML on macOS, TensorFlowLite on Linux, ONNX on Windows, TensorFlow not installed unless Python 3.11 or later | Installation, Usage |\\n\\n## Input rules, as the README states them\\n\\n- Accepted inputs are the sound files its version of librosa can read, including mp3, ogg, wav, flac and m4a.\\n- Stereo input is allowed but down-mixed to mono before analysis.\\n- Any sample rate is accepted and all audio is resampled to 22050 Hz before processing.\\n- Any length of audio can be processed, though very long files may be limited by available disk space, and the README suggests streaming the audio and processing windows at a time.\\n\\n## Polyphony and pitch bends: the exact claims\\n\\n- The README says a compatible audio file in gives a MIDI file out, complete with pitch bends, and that the tool is instrument-agnostic and supports polyphonic instruments.\\n- The README says it works best on one instrument at a time.\\n\\n## Stem-to-MIDI recipe for a DAW, from README statements (not tested)\\n\\n- Recipe from README statements, curator-assembled and not tested: (1) choose one instrument as a separate stem, since the README says it works best on one instrument at a time.\\n- (2) Run the command line with an output directory and the stem path, adding --save-note-events if a note list is wanted beside the MIDI file.\\n- (3) Take the MIDI file, which the README says comes with pitch bends, into the DAW to edit;
