Open a .sty file, edit the accompaniment on a piano roll, and play chords to hear it follow along — just like on the keyboard. Save a working style for your PSR-SX, Genos, Tyros or PSR. 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. Quandle Style Editor reads its sections (Intro, Main A–D, Fills, Ending) and every instrument part.
Pick a section and a part, then add, move, resize, copy or delete notes. Press play to hear the section — in your browser or through your own keyboard — and play chords on your keyboard to hear the accompaniment follow along in real time, the way the instrument does.
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 — Quandle Style Editor can't see your files, and neither can anyone else.
Brand new — and here's exactly what it already handles.
Both the classic PSR/Tyros format and the newer SFF2 used by PSR-SX and Genos. Full note editing with a safe, lossless save — verified on a real keyboard.
Play chords on your keyboard and the accompaniment follows in real time, transposed with the style's own rules — so what you hear in the editor lines up with the instrument.
The CASM data that makes a style follow your chords is kept byte-for-byte — you only ever change the notes.
Quandle Style Editor is free, and the core editor stays free. I build it around what players actually ask for — so if it helps you, or if something's missing, I'd genuinely like to hear it.
