The Pro Tools mix window: vocal, drum and reverb tracks with their inserts, sends, pans and the Drums mix group — The same mixer in both programs: pans, inserts in their original order, every send to its bus, and the Drums mix group.

The REAPER mixer after conversion: the same tracks, inserts, sends, pans and the Drums group — The same mixer in both programs: pans, inserts in their original order, every send to its bus, and the Drums mix group.

ValhallaVintageVerb open in Pro Tools, with its Decay automation lane — ValhallaVintageVerb on the reverb track. Every setting and the Decay automation match after conversion.

The same ValhallaVintageVerb in REAPER after conversion, every setting matching, with the same Decay automation — ValhallaVintageVerb on the reverb track. Every setting and the Decay automation match after conversion.

Avid's EQ3 7-Band open on the Snare Top track in Pro Tools, with a high-pass and five bands set — Avid’s EQ3 exists only for Pro Tools, so REAPER cannot load it. mollusk puts REAPER’s own ReaEQ in the same slot, set to the same curve and the same output gain. ReaEQ uses more bands than EQ3 to follow the same shape.

REAPER's ReaEQ on the same track after conversion, drawing the same curve — Avid’s EQ3 exists only for Pro Tools, so REAPER cannot load it. mollusk puts REAPER’s own ReaEQ in the same slot, set to the same curve and the same output gain. ReaEQ uses more bands than EQ3 to follow the same shape.

Pro Tools edit window: vocal, guitar and drum tracks in the colors Pro Tools assigned automatically — Track colors assigned automatically by Pro Tools are the same in REAPER. REAPER fills each clip with the color; Pro Tools colors the waveform.

The same tracks in REAPER after conversion, in the same colors — Track colors assigned automatically by Pro Tools are the same in REAPER. REAPER fills each clip with the color; Pro Tools colors the waveform.

A synth part in Pro Tools' MIDI editor, bars 205 to 210: two dark lines mark the edges of the clip, and the last note crosses the end line — The two dark lines in Pro Tools are the edges of a MIDI clip. Pro Tools plays only the notes that start inside the clip, and the last note rings past the clip’s end. In REAPER, the note that starts before the clip is kept and muted (the black bar at the left), and the clip is longer so the last note rings in full. REAPER colors each note by pitch and labels middle C “C4”; Pro Tools labels it “C3”.

The same part in REAPER's MIDI editor after conversion: the same notes, one muted note at the left edge of the clip, and the clip ending where the last note ends — The two dark lines in Pro Tools are the edges of a MIDI clip. Pro Tools plays only the notes that start inside the clip, and the last note rings past the clip’s end. In REAPER, the note that starts before the clip is kept and muted (the black bar at the left), and the clip is longer so the last note rings in full. REAPER colors each note by pitch and labels middle C “C4”; Pro Tools labels it “C3”.

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: Playlist comps, Elastic Audio edits and clip gain stay intact and editable.
Try it free: One session converts free and in full. Preflight reports are free for every session and show what would transfer.

Tested end to end on Pro Tools 12 and Pro Tools 2026. Sessions from Pro Tools 10 onward use the same file format and should convert.

mollusk converts sessions from one DAW to another with their mixes matching as closely as possible. Conversions are written in the destination DAW’s own format, not through AAF, OMF or similar. Pro Tools to REAPER is the first pair. Each pair is built and tested separately, against real sessions in both programs.

More pairs are planned. If there is a conversion you need, tell us which DAWs.
