Open a .sty file, edit the accompaniment on a piano roll, hear it, and save a working style for your PSR, Tyros or Genos. No install, works on any computer — and your files never leave it.
If you tweak or build styles for a Yamaha PSR, Tyros or Genos, you know the tools are old, Windows-only, and fiddly.
Mute a busy part, move a bass line, quiet a fill — small changes that make a factory or downloaded style fit your song.
Copy Main A into Main B and rework it — a fast way to grow a style without starting from scratch.
No Windows-only installer. It runs in your browser on Mac, Windows or Linux — open a page and go.
Three steps, all on your own machine.
Drag a style file onto the editor. MIDI Style Studio reads its sections (Intro, Main A–D, Fills, Ending) and every instrument part.
Pick a section and a part, then add, move, resize or delete notes. Press play to hear the section — in your browser, or through your own keyboard's sounds — before you commit.
Save a new .sty, copy it to a USB stick, and play it on your keyboard. The style's chord-response settings are kept exactly as they were.
Your style files are processed entirely inside your browser. Nothing is uploaded to any server — MIDI Style Studio can't see your files, and neither can anyone else.
This is an early, honest first version — here's exactly where it stands.
The style format used by most PSR and Tyros keyboards. Full note editing with a safe, lossless save.
The CASM data that makes a style follow your chords is kept byte-for-byte — you only ever change the notes.
Opens and reads SFF2 styles safely; deeper editing of the newer format is on the way.
MIDI Style Studio is free while I find out whether players actually want a tool like this. If it helps you — or if something's missing — I'd genuinely like to hear it.
