Edit MIDI notes, tracks, and controller data in one browser studio
Sunoi MIDI Editor is for creators who need editable note data, not only a finished audio render. Generate a starting pattern when useful, import a MIDI file, refine the piano roll, shape controller lanes, then export assets for a DAW workflow. Real editor view with track rail, piano roll, MIDI tools, and controller lane editing.
Supported MIDI Workflow
Formats, controller data, and browser limits in one place
These are the facts a producer needs before choosing a browser MIDI editor: what can come in, what can go out, what stays editable, and where a DAW should still take over.
Inputs
.mid, .midi, AI prompt, Web MIDI notes and controllers
Outputs
Standard MIDI, .aimg-midi.json project file, WAV preview bounce
Editing
Multi-track piano roll, snap, quantize, note tools, velocity
Automation
Pitch bend, CC1, CC7, CC10, CC11, CC64 controller lanes
Timing
Custom meter, 20-320 BPM, up to 256 bars
Browser support
Core editing works in modern browsers; Web MIDI is strongest in Chrome and Edge
Best use
MIDI handoff preparation, browser sketching, controller cleanup, and project recovery
Limits
SoundFont-style playback and WAV bounce are previews; final mix decisions still belong in a DAW
Professional MIDI Controls
Built for DAW handoff and note-level control
The editor keeps the details producers actually inspect: tracks, instruments, MIDI channels, note timing, controller data, browser playback, project recovery, and export formats.
Piano-roll editing
Compose directly on a note grid with octave labels, track focus, instrument assignments, channels, solo, mute, and note counts visible beside the roll. Draw and edit notes Manage multi-track parts Keep timing aligned to snap
Controller and automation lanes
Edit performance data below the piano roll so expressive MIDI details stay attached to the same musical timeline. Velocity bars Pitch bend lane Common MIDI CC lanes
Hardware input and preview
Record from Web MIDI where supported, audition parts with built-in playback or SoundFont-style presets, and keep fallback states clear. MIDI keyboard input SoundFont-style preview Built-in synth fallback
Project recovery and handoff
Save the browser project, restore local drafts, export standard MIDI for DAWs, or render a WAV preview for collaborators. Project file save/open Local draft restore MIDI and WAV export
Track rail detail
Track names, instruments, channels, note counts, solo, mute, and delete controls stay visible beside the piano roll.
Controller lane detail
Velocity, pitch bend, modulation, volume, pan, expression, and hold pedal editing share the same timeline.
Choose The Right Tool
Where MIDI Editor fits in the Sunoi workflow
Use MIDI Editor when editable note data is the goal. Choose a different Sunoi tool when your source or output is audio, lyrics, or a finished song draft.
MIDI Editor Online
Editing notes, tracks, channels, velocity, CC lanes, pitch bend, project files, and MIDI exports.
Use for note-level editingMIDI idea starter
Starting or importing editable MIDI material before refining notes and controller data in the editor.
Use inside the editorAudio to MIDI
Converting an audio recording, vocal idea, melody, or finished song into editable MIDI-style note data.
Use when audio comes firstText to Music
Creating browser audio or instrumental music from text when you want sound output instead of editable MIDI data.
Use for text-to-audioAI Music Generator
Generating a full song direction with arrangement, vocals, sections, and audio output from a prompt.
Use for full-song draftsOnline MIDI Editor Workflow
Edit an online MIDI project in four practical steps
The workflow stays close to how producers review MIDI: source material first, notes and tracks second, performance data third, then export or save when the idea is ready.
Start with editable MIDI material
Open the demo sketch, import a .mid or .midi file, or use AI MIDI generation when you need a starting idea.
Edit tracks and notes in the piano roll
Use the track rail, piano grid, snap controls, note tools, solo, mute, channels, and instruments to shape the arrangement.
Refine velocity and controller data
Adjust velocity, pitch bend, modulation, volume, pan, expression, and hold pedal lanes against the same time grid.
Save or export for production
Download standard MIDI, save a Sunoi project file, restore drafts, or bounce a browser WAV preview for review.
Export And Browser Reality
Clear output expectations for browser-based MIDI work
MIDI export is the production handoff. SoundFont-style playback and WAV bounce are useful for browser review, while final sound design can continue inside your DAW.
MIDI for DAW handoff
Export standard MIDI for Ableton, Logic, FL Studio, Cubase, notation tools, and other production environments.
Project restore
Save and reopen Sunoi project files when you need to keep tracks, automation, snap, zoom, tempo, meter, and draft state.
WAV preview bounce
Bounce a quick audio preview for checking arrangement shape, while keeping MIDI as the editable source of truth.
MIDI Editor Online FAQ
What is an online MIDI editor?
An online MIDI editor lets you edit note timing, pitch, velocity, tracks, channels, and controller data in a browser piano roll without installing a DAW first.
What is the Sunoi MIDI editor best for?
Use it for AI-assisted MIDI sketching, note-level editing, controller-lane cleanup, Web MIDI recording, project recovery, and MIDI export for DAW handoff.
Which files can I import and export?
You can import .mid and .midi files, save an .aimg-midi.json project file, export standard MIDI, and bounce a WAV preview from the current browser arrangement.
Does the editor support MIDI controller lanes?
Yes. The editor includes velocity plus pitch bend and common CC lanes such as modulation, volume, pan, expression, and hold pedal.
Can I record with a MIDI keyboard?
Supported browsers such as Chrome and Edge can use Web MIDI input for note recording, velocity capture, selected CC messages, and pitch-bend data on the active track.
Which browsers support Web MIDI recording?
Core editing works in modern browsers. Web MIDI input depends on browser support and is best treated as a Chrome and Edge workflow, with clear fallback messaging when hardware access is unavailable.
Does SoundFont playback replace a full DAW instrument setup?
No. SoundFont-style presets are designed for practical browser preview. Export MIDI when you want to finish the sound design with dedicated DAW instruments or plugins.
Can the exported MIDI open in Ableton, Logic, FL Studio, or Cubase?
Yes. Standard MIDI export is intended for common DAWs and notation tools, while the Sunoi project file keeps editor-specific draft state for later browser editing.
How is MIDI Editor different from Audio to MIDI?
Use MIDI Editor when you already have note data or want to compose notes directly. Use Audio to MIDI first when the starting point is an audio recording, vocal line, or finished song.
Does Sunoi support tempo maps or advanced DAW automation?
The browser editor focuses on global tempo, custom meter, note editing, common CC lanes, pitch bend, project files, and export. Complex tempo maps and plugin automation still belong in a DAW.
Open the browser MIDI editor and refine the notes yourself
Generate a sketch, import MIDI, edit controller data, save the project, and export MIDI or WAV preview assets from one focused workspace.
