You know how painful this used to be.

Converting a style the old way meant one of two things: hours inside Cubase or Logic, reverse-engineering MIDI tracks you didn't write — or an afternoon buried in vendor spec PDFs trying to figure out why the drums are landing wrong. And that's if you even knew where to start. Most players gave up and rebuilt from scratch. Or kept the old keyboard they didn't want anymore.

For players

You switched keyboards — or found the perfect style in the wrong format. Either way, your music shouldn't stop. Load your Yamaha styles on Korg. Bring your Ketron grooves to Yamaha. Keep playing, without starting over.

For style creators

You've spent hours — sometimes days — getting a style to sound right. The last thing you want is to rebuild it by hand for every keyboard platform your buyers own. No more opening DAWs just to reformat files. No more managing conversion spreadsheets. No more losing a sale because your style only ships in one format. Convert your library once. Reach everyone.

Features

Built for the way you actually work

Your style plays in tune — not just structurally correct, but musically right

The conversion engine adapts harmony and structure for the destination keyboard so the result feels like it was built there, not ported over.

The groove survives the switch

Drum parts land on the closest equivalent sound on the target keyboard. The feel stays intact even when the kits don't match perfectly.

You're in control before anything downloads

Anything the engine isn't certain about gets flagged for your review. Approve with one click or override individual mappings — you always have the final say.

Convert your whole library, not just one file at a time

Batch conversion, saved drum maps, and Studio tools let you move large collections across platforms without repeating the same decisions on every file.
