MeluMimi
Piano MIDI workflow
Turn a piano recording into a practical editing starting point: download the MIDI, open it in a DAW or piano-roll editor, then review notes, timing, velocity, and sustain before using it in a music project.

This 15-second source recording and its 191-note MIDI are the same unedited files published in our transparent product test. Listen to the source, then download the MIDI and follow the steps below.
The same MIDI can be cleaned for a natural performance or tightened for an arrangement. Start with the goal of the track.
Keep expressive timing and velocity while correcting only audible false or missing notes. This is usually the best starting point for a piano performance.
Best next check: note accuracy, note endings, velocity balance, sustain behavior, and the chosen virtual piano.Use a compatible DAW when you want to change the piano sound, correct timing and velocity, add instruments, or build a track.
Best next check: grid strength, note length, velocity range, sustain, tempo alignment, and interaction with other instruments.Use a clear piano-only or piano-focused MP3, WAV, M4A, FLAC, or supported video. Reduce background noise, clipping, room echo, vocals, and other instruments. Only upload media you own or are allowed to process.
Upload the recording to MeluMimi, choose the sustain option that matches your editing goal, submit the job, preview the result, and download the .mid file. The output is editable MIDI note and performance data—not rendered audio.
Use your editor's MIDI import command or supported drag-and-drop workflow. If the file opens silently, assign a software instrument: MIDI describes musical events, so the sound comes from the instrument used for playback.
Compare the MIDI against the original recording. Correct unwanted or missing notes first, then timing, duration, velocity, and sustain behavior. Keep the untouched download as a separate version so every edit remains reversible.
Exact menus and supported controller data vary by editor. Use its MIDI import workflow and verify the result rather than assuming every editor behaves identically.
Create or select a MIDI or instrument track, then import the downloaded .mid file using the editor's supported command. Drag-and-drop is another option only when that editor supports it.
Check where the clip starts and whether the editor changed the project tempo. Keep the original download unchanged.
Load a piano or another suitable software instrument on the track before judging playback. Open the piano roll and compare a short passage with the original recording.
MIDI is performance data, not recorded sound. Instrument choice affects the audible result even when the notes are unchanged.
Inspect note beginnings and endings, velocity and, when included, CC64 sustain events. Confirm that the destination editor and instrument actually retain and respond to the controller data.
Save corrections as a separate version. Avoid automatic heavy quantization before comparing against the source.
No. MIDI stores notes and other musical events. A DAW or MIDI editor uses an instrument to turn those events into sound.
Not automatically. Playback depends on the virtual instrument, velocity, note length, and sustain behavior in the destination software.
Usually not. Start with false notes and obvious timing errors, then apply light or partial quantization only when the arrangement needs a tighter grid.
Check note accuracy and note endings first, then velocity balance and sustain-pedal behavior. Those changes usually affect the result more than cosmetic edits.
Use the original recording and unedited MIDI to check what this example demonstrates. One example is not a universal accuracy score.
Convert a short, clear passage first. Download the MIDI, complete one cleanup pass, and only then decide whether the result is useful for the full recording.
