How Do I Turn a MIDI File into a Piano Roll Video?
Three steps, no manual — from file to flowing notes in under a minute.
Step 1 — Drop in your MIDI file
Drag a .mid or .midi file onto the tool above, or hit "Try a demo". The file is read locally — nothing is sent anywhere. Demos are real MIDI files, so you can watch the visualizer work before touching your own music.
Step 2 — Pick a piano theme
Choose a look — classic ivory, concert dark, neon night — or build a custom palette for your channel. Dark themes with note glow read best on video; ivory suits a clean classroom look.
Step 3 — Play, record & share
Press play and watch the piano roll flow at 60 fps. Hit record to capture video or grab an HD snapshot — free, no watermark. Go full-screen first for the cleanest recording — one key hides the whole interface.
A MIDI Visualizer Built for Speed
Every visualizer shows notes. This midi visualizer is built to stay smooth when the notes get dense — in your browser, with your files staying yours.
Real-time 60 fps piano roll
Notes glide across the piano at 60 fps with hardware acceleration — sample-accurate, even on dense files. The denser the file, the more the smoothness matters: orchestral MIDIs with thousands of notes stay fluid where other visualizers stutter.
One-click video recording
Record your session straight from the page and download the video — no watermarks, no time limits. Press record, play the song, stop when it ends; the file is yours to post anywhere.
Piano theme skins and custom colors
Classic ivory, concert dark, neon night — or your own palette, so every upload matches your brand. Set background, key colors, and note glow once, then reuse the palette on every video you make.
Zen full-screen mode
One key hides the entire interface — a clean stage for recording, streaming, or projection. No menus, no chrome, just the piano and the falling notes.
Per-track colors
Multi-track MIDI files get their own color per track, so you can follow each instrument through the densest passages. Type 0 and Type 1 both play; the colors keep the parts apart.
100% local, nothing uploaded
Your MIDI file is read by your browser and never uploaded, stored, or shared — close the tab and nothing remains. No sign-up needed to visualize, and no account means no personal data to protect.
Your MIDI File, Visualized in Seconds
Drop in a .mid and watch it flow — free, no sign-up, no watermark.
Every demo in this midi visualizer is a real MIDI file — tap one and watch the notes fall. Pick a theme, hit record, and you have a watermark-free video in minutes.
MIDI Visualizer FAQ
Questions people actually ask before visualizing — answered straight, no marketing fluff.
Is this MIDI visualizer free?
Free to use — no sign-up needed. Guests get 1 full visualization; signed-in users get unlimited visualizations.
Does it run locally, or is my MIDI file uploaded?
100% locally. Your MIDI file is read by your browser and never uploaded, stored, or shared — close the tab and nothing remains. No account, no upload queue, no waiting room — the file never leaves your machine.
Can I export the visualization as an HD video without a watermark?
Yes. Hit record, play the song, download the capture — free, watermark-free. HD snapshots work the same way, at any moment, with no time limits on either.
Can I customize the theme to match my brand?
Yes. Beyond the built-in piano theme skins, set your own background, key colors, and note glow — save the palette once, reuse it on every video.
The notes seem out of sync with the audio. What should I do?
Check your audio path first — Bluetooth adds delay, so try wired audio. Then reload the page, keep the tab in the foreground, and close CPU-hogging apps.
Can I use the visualization video for my YouTube or TikTok content?
Yes, including commercial use — monetized YouTube videos, TikTok posts, client work, no attribution required. One caveat: only visualize music you own or are licensed to use. The license covers the video you make; the music itself still needs to be yours to use.
How do I make piano videos like the ones on YouTube, with background art and glowing notes?
Pick a dark theme with note glow, set your own background, go full-screen, and record. Piano roll plus brand colors plus background art is the formula behind most viral piano visualizer midi videos.
Can I open a MIDI file I made in my DAW?
Yes — any standard .mid or .midi file, from Ableton, FL Studio, Logic, Cubase, or MuseScore. Type 0 and Type 1 both play; multi-track files get per-track colors.
What is the difference between this page and Midivisualizer?
This midi visualizer is the watch-it-live tool: drop a file and see the piano roll flow in your browser. Midivisualizer is the export sibling for shareable video files — different job, same local engine.
Do I need an account to try the demo tracks?
No — the four demos load with no account at all. The free quota only counts visualizations of your own uploaded files: guests get 1, signed-in users get unlimited visualizations. Demos are the fastest way to see the themes in action before committing your own file.
Will it stay smooth on dense orchestral files?
Yes — the piano roll renders at 60 fps with hardware acceleration and stays sample-accurate even on dense files. Per-track colors help too — each instrument keeps its own color through the pile-up. If a huge file stutters, close other tabs and keep this tab in the foreground.
Can I capture a still image, not just video?
Yes — grab an HD snapshot at any moment, free and watermark-free, the same way recording works.
Which browsers are supported?
Any modern browser with Web Audio and hardware-accelerated canvas: Chrome, Edge, Firefox, and Safari on desktop, tablet, and phone. Because this midi visualizer is pure browser tech with zero server, it even works on locked-down machines like Chromebooks. If a file stutters, close other tabs and keep this one in the foreground.
What do Type 0 and Type 1 mean on the demo cards?
Type 0 packs every note into a single track; Type 1 keeps parts on separate tracks with their own colors in the visualizer. Both play identically — the difference only matters when you start following individual parts.
Can I use my own background image?
Yes — beyond the built-in piano theme skins, set your own background, key colors, and note glow. Save the palette once and reuse it on every video.
How do I tell instruments apart in a dense file?
Every track gets its own color in the piano roll, so you can follow each instrument through the densest passages. Type 0 and Type 1 files both work.
What is a piano roll?
A piano roll is a scrolling grid where each note appears as a bar — pitch on the vertical axis, time on the horizontal. This midi visualizer turns your MIDI file into that flowing view in real time. Pitch runs bottom-to-top like piano keys; time scrolls left to right.
Does it work on phones and tablets?
Yes — any modern mobile browser with Web Audio and hardware-accelerated canvas. Drop a .mid file from your device and watch it flow.
Can I use it offline?
The visualizer runs 100% locally in your browser — once the page is loaded, no network is needed to play or record.
Does recording capture my theme settings?
Yes — what you see is what records: theme, colors, glow, and full-screen all carry into the capture. Set the look first, then press record.
What does 60 fps mean for my video?
Sixty frames per second means the notes glide instead of jumping — the motion stays smooth even in fast passages, and your recording inherits that smoothness. Even a phone screen shows the difference between 60 fps glide and choppy motion.
