A cleanup order for converted MIDI

How to Clean Up Converted MIDI starts with a repeatable order: contour, ghost notes, octaves, timing, duration, and velocity.

A MIDI draft can preserve the note sequence, approximate timing, duration, dynamics, and a usable view of repeated musical patterns.

Keep the original audio aligned in the same session and use a plain MIDI sound that makes pitch and timing errors obvious.

Editing from the piano roll alone encourages visual perfection, over-quantization, and deletion of quiet notes that matter in context.

Fix global octave and alignment issues, work phrase by phrase, remove definite ghosts, correct durations, then decide on quantization and velocity.

In this workflow, quality is proven by the edit, not the upload screen.

This workflow earns its place when the draft removes more work than it creates.

Only upload audio that you have the right to process.

Every answer below is visible in the HTML and follows the same boundaries as the upload flow.

What should I clean first in converted MIDI?

Clean pitch and note segmentation first, then use the smallest timing adjustment that serves the arrangement.

How do I find ghost notes quickly?

Look for isolated octave duplicates, very short fragments, and events that appear after reverb tails, then confirm by listening.

When should I reconvert instead of edit?

When an entire passage has the wrong contour or requires event-by-event rebuilding, a cleaner source is usually faster.
