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; messages pages |\n| Channels, notes, data bytes | Channels 0 to 15; note 0 to 127; data bytes 7 bits. | channel, note | intro; message types; about MIDI |\n| Delta time | Integer ticks inside a track; seconds from play() and iteration. | time | MIDI files; messages pages |\n| Resolution | Fixed tick; ticks per quarter note; typical 96 to 480. | ticks_per_beat | MIDI files page |\n| Tempo | Microseconds per quarter note, default 500000, 120 BPM at 4/4, 60 at 2/2. | set_tempo, bpm2tempo, tempo2bpm | MIDI files; meta message types |\n| Conversion | tick2second and second2tick; integer rounding might be necessary. | tick2second, second2tick | MIDI files page |\n| Time and key signature | Default 4/4 since 1.2.9; key from a fixed list. | time_signature, key_signature | meta message types |\n| End of track | Empty meta message; one is written if absent. | end_of_track | meta message types; MIDI files |\n| File types | 0 single track, 1 synchronous, 2 asynchronous; type 0 needs exactly one track. | type | MIDI files page |\n| Playback length | Seconds, for types 0 and 1 only. | length | MIDI files page |\n| Unknown meta messages | Returned as UnknownMetaMessage; saved back exactly. | UnknownMetaMessage | meta message types |\n| Features, as the README lists them | Full support for MIDI files (read, write, create and play). | MidiFile | README.rst |\n| Basic Pitch record, revision 1 | MIDI out with pitch bends; note range from a frequency range in Hz. | upstream step only | record |\n| Tools pointer record, revision 1 | Mido row: MIT and README SPDX line; evidence status as written. | pointer only | record, mido row |\n| Licence | LICENSE headed The MIT License; README says MIT.
