Convert MYR to MIDI

A sequencer, hardware keyboard, or notation application may require a Standard MIDI File instead of a Myriad project. Converting the project makes its musical events editable and playable elsewhere, but it does not preserve the exact rendered audio.

What the MYR format is

MYR is the proprietary native project format used by Myriad’s Melody Assistant and Harmony Assistant. It can contain score notation, notes, rhythms, lyrics, staff configuration, tempo and playback settings, instrument assignments, and other information needed to edit and play a composition in Myriad software.

What the MIDI format is

MIDI is an event-based format rather than an audio recording. A Standard MIDI File stores events such as note-on and note-off messages, pitch, velocity, timing, tempo, program changes, controller data, and sometimes lyrics or other metadata.

MIDI files are usually much smaller than rendered audio and can be imported into digital audio workstations, synthesizers, hardware keyboards, and notation programs. The receiving device or application supplies the sounds, so the same MIDI file can produce different audio on different systems.

How to convert MYR to MIDI

1. Install Myriad Harmony Assistant or Melody Assistant for the operating system supported by your version. Harmony Assistant is generally the better choice for projects using complex scores or playback arrangements.
2. Open the project with File → Open and select the .myr file.
3. Review the score, tempo changes, staff assignments, muted parts, and instrument settings. Exclude unwanted staves or parts through the export options if the destination should contain only selected material.
4. Use the application’s MIDI export command, normally File → Export → MIDI or File → Export → MIDI file. The exact wording can differ between Myriad releases.
5. Choose the destination and save the file with a .mid or .midi extension. Keep separate tracks or channels when the destination needs independently editable instrument parts.
6. Open the exported file in the target DAW, notation program, or hardware sequencer. Assign instruments again if necessary, then check timing, channel routing, tempo, dynamics, and articulations.

Online converters and alternatives

There is no broadly established, reputable online converter that can be relied on for arbitrary Myriad .myr projects. Many browser-based services accept only WAV, MP3, FLAC, or other common formats and cannot interpret MYR. Use Myriad software for the conversion; upload a file to an online service only when that service explicitly documents support for Myriad MYR files and the project contains no sensitive material.

If Myriad software is unavailable, ask the sender to export MIDI from Harmony Assistant or Melody Assistant. Converting a rendered MYR audio export to MIDI with an audio-to-MIDI service is a different process and normally produces less accurate notation than exporting the original score data.

Quality and compatibility limits

MIDI export transfers musical events, not Myriad’s synthesizer output. Sound libraries, effects, mixing, notation layout, page formatting, lyrics presentation, and score-specific playback behavior may be lost or interpreted differently. MIDI can carry some lyric and controller events, but support varies between applications.

Check repeats, alternate endings, tuplets, grace notes, ornaments, articulations, tempo changes, and dynamics after import. Some playback directions do not have a direct MIDI equivalent. Receiving software may merge tracks, remap programs, restrict channels, or ignore instrument changes; channel 10 is conventionally used for percussion under General MIDI, but this convention is not universal.

If the requirement is identical sound rather than editable notes, export or render the MYR project to WAV or another suitable audio format instead of MIDI.
