Sometimes a MIDI part is nearly there: one note has wandered too high, another hangs on too long, and a third has decided it’s the soloist. AudioFlow’s Piano Roll is handy for these small edits.
Open an existing MIDI file using Edit MIDI on the MIDI tile or Open in Piano Roll… in its menu. You can change note pitch, length and velocity, undo and redo edits, and export the result.
Here’s a simple order to work through:
1. Pitch. Find a note that sounds out of place and adjust it. Start with a short passage; it’s easier to hear what needs attention.
2. Length. Check where each note ends. Shorten one that carries on longer than intended, or extend one that feels too short. Listen to the transition into the next note after each change.
3. Velocity. Check the accents. Lower a note that feels too insistent or raise one you want to emphasise. Every note doesn’t need the same value.
After converting audio to MIDI, check for ghost notes: short or quiet extra notes that may have appeared during transcription. Listen to the passage, remove accidental notes, and adjust the length and velocity of the ones you want to keep. Don’t delete every quiet note: some are part of the performance’s character.
During playback, Catch Playhead keeps the playhead in view, while playing notes light up in colours based on velocity. That makes the part easier to follow, but your ears still get the final say.
Once the passage feels right, export your edit and keep the original MIDI separately. Take small changes one at a time: adjust, listen, move on.
