DAW conversion tool

ptx2rpp Pro Tools to REAPER

Your Pro Tools mix opens in REAPER. Sounding like it should.

Convert one of your sessions for free and get a preflight report for your whole library.

Plug-in settings intact
Supported plug-ins keep their exact settings, from EQ curves to synth patches. The report lists any that cannot be transferred.
Pro Tools not required
mollusk reads .ptx files directly. No Pro Tools installation, subscription or plug-in license is needed to convert.
Built for real-world sessions
Vocal comps built across many playlists, Elastic Audio timing edits and clip gain rides all arrive intact and editable.
Try it free
Convert one complete session at no cost, with every track, bus and plug-in. Preflight reports are free for every session, so you can see what would transfer from each one.

Tested end to end on Pro Tools 12 and Pro Tools 2026. Sessions from Pro Tools 10 onward are the same family of file and should convert.

Each item is verified against real sessions. Anything mollusk finds but cannot transfer is listed in the report.

mollusk began as one question: can a session arrive in another DAW exactly as it was left, rather than approximately? Pro Tools to REAPER is the first pair. Every pair is built and tested on its own, because a conversion is only as faithful as the attention given to both DAWs.

More pairs follow. Which ones depends on what people ask for. If there is a conversion you need, tell us which DAWs.

Coming soon to Windows, macOS and Linux. Email us to be notified at release.
