Sketch notes quickly
Place melodies, chords, bass movement, or rhythmic ideas without opening a full production session.
MIDI Editor
Compose and edit MIDI notes
Visual note editing
A browser MIDI editor for turning rough notes into usable musical parts.
Use the piano roll as a focused place to compose, correct, and understand MIDI. It keeps note pitch, timing, velocity, and phrase shape visible, so you can move from a quick idea to a part that is ready for production or practice.
Shape timing and feel
Move notes, stretch phrases, refine velocity, and tighten rhythm until the part feels intentional.
Carry the idea forward
Use MIDI as a portable bridge between recording, songwriting, arrangement, learning, and DAW production.
Editing tips
Make MIDI musical, not just correct
Fix note boundaries first
Start by cleaning starts, endings, and accidental overlaps so the phrase plays clearly.
Use velocity for expression
Small velocity changes can make a simple pattern feel performed rather than programmed.
Compare with the source idea
When editing converted MIDI, keep the audio memory nearby and preserve the phrase that made the idea work.
Audio-to-MIDI handoff
Clean up converted audio instead of starting over.
If a melody began as audio, convert it first, then open the result here. The editor lets you fix extra notes, align timing, and reshape the phrase while keeping the original musical idea intact.
Convert audio to MIDISongwriters
Capture hooks
Turn a melody sketch into notes you can revisit, transpose, and develop into a full song.
Producers
Test parts fast
Draft bass lines, chord movement, counter-melodies, and transitions before committing them to an arrangement.
Learners
Study structure
See pitch, timing, and note length visually so practice material is easier to understand and adjust.
Note editing glossary
The controls that turn MIDI data into a musical phrase
A piano roll is more than a note grid. Each edit changes a different part of how the listener hears the performance.
Pitch
Move a note vertically to correct the melody, transpose a phrase, rebuild a chord, or fit a bass line to the harmony.
Start time
Move a note horizontally to repair an early or late entrance. Preserve small offsets when they are part of the groove.
Duration
Shorten overlaps for clarity or extend sustained notes so the phrase connects naturally. Note endings often matter as much as attacks.
Velocity
Vary note intensity to create accents, shape a crescendo, and avoid the mechanical sound of every event playing at one level.
From capture to arrangement
A practical MIDI workflow from audio idea to DAW
Use the editor as the decision point between a rough capture and a part that is ready to orchestrate, share, or produce.
Import or sketch
Begin with converted audio or draw a melody, chord sequence, or bass line directly. Keep the first pass focused on the core musical idea.
Correct, then humanize
Fix wrong notes and awkward overlaps before adjusting groove and velocity. Apply quantization selectively so precision does not erase expression.
Test in the arrangement
Choose an instrument, listen against the rest of the song, and revise register or density. Export the MIDI when the part supports the production rather than competing with it.
Convert a recording into editable notes
Turn a clean vocal, melody, or instrumental performance into a MIDI draft, then open it here for detailed correction.
Prepare stems before note conversion
Separate a busy mix into focused production tracks when you need a cleaner source for audio-to-MIDI tracing.
