/play — Load & Explore MIDI Files
Use the Mozart MCP tools to load, inspect, and navigate MIDI files.
Quick Start
/play song.mid
Workflow
- Load the file with
load_midi— provide the path and an optional alias - Inspect with
midi_info— see tracks, instruments, tempo, time signature - Browse measures with
get_measures— view notes by measure number - 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

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_notesto find specific patterns before editing - Track indices are 0-based — check
midi_infoto see what's on each track
