/play — Load & Explore MIDI Files

Use the Mozart MCP tools to load, inspect, and navigate MIDI files.

Quick Start

/play song.mid

Workflow

1. Load the file with load_midi — provide the path and an optional alias
2. Inspect with midi_info — see tracks, instruments, tempo, time signature
3. Browse measures with get_measures — view notes by measure number
4. Search with search_notes — find notes by pitch, track, or range

Examples

Load and summarize

load_midi file_path="song.mid" alias="song"
midi_info alias="song"

Show measures 1-8 of track 0

get_measures alias="song" start_measure=1 end_measure=8 track=0

Find all C notes in the melody

search_notes alias="song" note_name="C" track=0

Show measures around a key change

get_measures alias="song" start_measure=33 end_measure=36

Tool Reference

Tool	Purpose
load_midi	Parse a .mid file and load it into memory
midi_info	Show tempo, time sig, tracks, instruments, pitch ranges
get_measures	Get notes organized by measure (tempo/time-sig aware)
search_notes	Search notes by pitch, name, track, or measure range
list_loaded	Show all loaded MIDI files
unload_midi	Remove a file from memory

Tips

• Use short aliases (e.g. "song", "bass") to make commands readable
• Browse a few measures at a time — large ranges produce a lot of output
• Use search_notes to find specific patterns before editing
• Track indices are 0-based — check midi_info to see what's on each track
