Release notes

mollusk 1.2

New

REAPER projects convert to Pro Tools sessions: tracks, audio, MIDI, routing, sends, the mix, automation, takes, tempo, markers and video
REAPER to Pro Tools: fades and crossfades in REAPER's shapes, item volume and take volume envelopes as Clip Gain, play rate, stretch markers and pitch shift as stretched and warped clips, and looped items as one clip per pass
REAPER to Pro Tools: folders arrive as Pro Tools routing folders, nested as in REAPER, and REAPER's track groups as Pro Tools mix groups, VCA masters included
REAPER to Pro Tools: surround and multichannel tracks up to 7.1 arrive as one track of their width, and sidechain inputs and the extra outputs of multi-output instruments keep their routing
REAPER to Pro Tools: REAPER's EQ, compressor and gate arrive as Avid's EQ3 and Dyn3 with their settings, and Volume Adjustment and Channel Polarity Control as Avid's Trim. The setting Replace REAPER's stock plug-ins with Avid's turns this off
Plug-in settings come across from REAPER to Pro Tools wherever the settings can be read, among them FabFilter, Valhalla, u-he, iZotope, Arturia, Line 6, TDR and Antares, also for plug-ins that are not installed on the converting computer. Plug-in automation comes across on the controls mollusk has verified
REAPER to Pro Tools: a plug-in that cannot be written keeps its place in the chain as an inactive insert under its own name, and a chain longer than the ten inserts a Pro Tools track holds continues on an aux track right after the track
Melodyne edits come across from REAPER to Pro Tools clip by clip. Melodyne is needed in Pro Tools to play them
REAPER to Pro Tools: video in .mp4, .mov, .m4v and MXF files, ProRes, DNxHD and DNxHR included, arrives on Pro Tools video tracks. On Windows the video's own sound comes across too, on an audio track, as REAPER plays it
REAPER to Pro Tools: MP3, FLAC, OGG and Opus files are decoded into the session, and audio at another sample rate than the session's is converted to the session's rate
REAPER to Pro Tools: an item whose audio file is missing arrives as an offline clip in its place, so Pro Tools lists the file under Missing Files and Relink brings the audio back
REAPER to Pro Tools: track and item colors, track notes as comments, and project notes as a memory location named Project notes. Hidden tracks stay hidden
REAPER's own backup copies (.rpp-bak) are listed in the library when Display backups is ticked, and convert with their audio found where REAPER finds it
A report beside every Pro Tools session written names anything that did not come across
REAPER projects have a bucket of their own in the library, the queue and Conversions. The free trial covers one project, from Pro Tools or from REAPER
REAPER to Pro Tools has settings of its own in the same places as Pro Tools to REAPER: the settings drawer, a bucket's settings and a session's settings window. Among them are Drop alternate takes, Leave out hidden tracks, Use Pro Tools fades only, and Track colors and Clip colors
The conversion reports in both directions are worded formally throughout, with correct singular and plural forms. NOT WRITTEN lists only what is missing. What arrived in another form has its own WRITTEN DIFFERENTLY list, and a conversion with only that list is no longer marked as needing a look
Pro Tools to REAPER: plug-ins the converting computer's REAPER has not listed yet, or with no REAPER installed there, now arrive with their settings for many makers, among them TDR Nova, TAL-NoiseMaker and Antares' AVOX line
Pro Tools to REAPER: a plug-in mollusk does not recognize now keeps its place in the chain as a named, bypassed slot, so the plug-ins after it stay in Pro Tools' order
The library can be one folder or whole drives. With Whole drives, the library lists the projects on every drive that is ticked. On Windows, Fast search of this computer, an optional background service in Preferences and in Setup, lists them in seconds instead of a long scan
On Windows, with Copy media into project and Fast search on, an audio file a session or project is missing is found by name and copied in when exactly one file on the computer has that name. The report names each file found and where the file came from
A queue bucket can have settings of its own for a run, between the settings strip and a session's own settings
The library has a DAW filter: the funnel button chooses which programs' projects are shown, and a bucket's right-click menu can hide its program
A library scan can be stopped. The scan button reads Stop under the pointer, and the library stays as it was before the scan
Conversions has a Group by DAW tick box. Unticked, every conversion is in one list by date and time
A double click on a queue row opens the session's settings, and the settings window shows the session's name in a box for renaming
When a run finishes, mollusk switches to Conversions, where the projects just written are listed
App settings is now called Preferences, in the Help menu as before

Fixed

Pro Tools to REAPER: a send panned in Pro Tools now plays at the right level in REAPER. It played louder on the side it was panned to
Pro Tools to REAPER: MIDI on an instrument track in some sessions, among them Avid's demo session Can't Get Enough, now arrives on its instrument track instead of on an extra track at the end
On a Mac, Command+, now opens Preferences
On a Mac, a click outside mollusk no longer closes an open small window such as Preferences
Open folder when finished (Show in Finder when finished on a Mac) now opens the folder when the run finishes, with the project selected when one project was converted
On a Mac, Notify when finished now shows a notification. macOS asks once, when mollusk opens, whether mollusk may send notifications, and the queue says so when notifications for mollusk are off
A queue row's buttons, name, tick box and settings could be changed during a run. They are now locked until the run ends
With a filter typed, Select all and Deselect all now tick or untick only the rows the filter shows
A large library now filters as fast as a search is typed, switches views at once, and no longer freezes the window when a scan finishes
Quitting mollusk, or restarting mollusk for a new text size, during a library scan no longer waits for the scan to end
Reports in the app keep each line as the converter wrote the line and scroll sideways in a narrow window, instead of breaking lines a second time
mollusk now removes its temporary folders when it closes, and clears the ones a closed or crashed copy left behind at the next start

mollusk 1.1

New

The library, the queue and the Conversions tab group files by program in buckets. Each bucket has a color, a fold arrow, an on/off switch and a settings button. Click a bucket header in the library or Conversions to fold it. Collapse all and Expand all animate, and folding is an undo step
Drag a whole library bucket into the queue, like a folder. Queue all, a dropped folder and Add folder ask first when they would add more than 500 sessions
A bucket in the queue shows the total size of the media it will copy when Copy media into project is on
The settings drawer has four lanes: every conversion, the source, the source and destination pair, and the destination. Each lane has Reset for the settings changed in that lane, and scrolls on its own when the window is short. Default in the preset bar is always mollusk's own settings
Presets are one list. A preset saved from the preset bar or from a session's settings window appears in both. Options in the preset menu holds Rename and Delete, and a deleted preset comes back with Undo
A session's settings window (the gear) has its own Save to and Report folders, a Name suffix with an explicit No suffix choice, and Follow strip, On or Off, for each setting. The gear turns blue when a session has settings of its own. Clicking the x keeps the changes
Save to offers the destination's default projects folder, a folder beside the source, or a custom path. The bottom bar names each choice
A run asks for confirmation before it copies 50 GB of media or more, or more than half of the free space on a drive. The amount is set in Preferences, from 1 to 999 GB. The window lists each drive, named as Explorer names it, with what it will copy and how much room it has before and after. A run that cannot fit stops before anything is written
Preferences has DAW colors, one color for each program from a palette of 42 shades, with Restore all default colors. Export settings and Import settings save and load the settings, presets and DAW colors as one file
Keep a record of each run, in the settings drawer (off by default): a folder with a summary and a checksummed list of the originals and the projects written
Up and Down in Conversions walk through the reports, and the middle mouse button scrolls the long lists
Each master fader after the first arrives as a track, and the tracks routed to that master fader play through the track
Tracks wider than 7.1, up to 9.1.6 and fourth-order Ambisonics, arrive as one track with all of their channels, and surround aux and routing folder tracks keep their width
A session saved by a Pro Tools version mollusk has not been tested with, such as Pro Tools 10 or 11, says so in its report, with a request to send the session in

Fixed

In sessions saved in Pro Tools 2026 with a Basic folder, renamed tracks arrived under their old names, a clip could land on an extra track, and a track color could move to the track before. Names, clips and colors now match Pro Tools
A folder with nothing in it no longer takes in the tracks that follow
Alternate playlists in sessions saved in Pro Tools 2026 arrived as separate muted tracks. They now arrive as lanes under their own track
Clip Gain on a clip with warp markers now moves with the audio, as in Pro Tools
Helix Stadium Native on a mono track played 6 dB quieter than in Pro Tools. The level now matches
An Avid Trim with polarity switched on flipped its track after every plug-in, so plug-ins after the Trim and pre-fader sends heard the track upright. The flip now sits in the Trim's own slot, as in Pro Tools
Stretched clips on an Elastic Audio track set to Varispeed kept their pitch. They now change pitch with their speed, as in Pro Tools
Automation of u-he plug-ins such as Diva and Podolski now reaches the right controls
The Mid Frequency of Softube's Tube-Tech Classic Channel played higher than set from its third position up, for example 4 kHz as 7 kHz. The frequency now matches Pro Tools
MIDI notes muted in Pro Tools 2026 played in REAPER. They now arrive muted
Video tracks keep their place in the track order
With more than one video track, REAPER shows the picture of the track Pro Tools plays, and the other video tracks arrive muted
The library stays responsive and uses far less memory with thousands of sessions. Rescan runs in the background, and filters match program names and file types
Searching the library opens every folder with a match. Clearing the search restores the folders as they were
Small windows close with their own button or Escape. A click outside a window no longer closes the window
The queue stays put when rows above the view are cleared, and clearing, sorting or undoing in a bucket no longer leaves a gap under its header or a row faded out
Undo and Redo step one change at a time, also when the key is held, and bring back a cleared bucket the way it was
A background check that cannot read a session marks the row red, and a row removed from the queue stops being checked at once
Clicking a row's buttons, name, tick box or grip no longer highlights the row
The time left on a run follows the work that is really done, and the progress bar no longer counts a shared media folder more than once

mollusk 1.0.2

Fixed

Volume automation ramps play as in Pro Tools between their breakpoints (fades by automation no longer hang loud on the way down)
Fades and crossfades keep their Pro Tools length and shape, on tick-based tracks and on clips stretched with Elastic Audio as well
Clip positions match Pro Tools in long sessions, on tick-based tracks and for clips stretched with Elastic Audio
Overlapping clips on a track play as Pro Tools shows them
Clip gain ramps play as in Pro Tools between their points
Sessions at Pan Depth -6.0 keep their panned levels exactly
A video track is silent in REAPER, as in Pro Tools; the video's sound stays on its own audio track

Removed

Recover deleted clips, in Settings, is removed. Projects came out the same with the setting on and off: what it reported as deleted clips were fades sharing a number with a clip, which is fixed, and a clip deleted and saved in Pro Tools leaves no position in the session file to recover. The report still names any clip left out

New

A Pro Tools master fader with plug-ins, set away from 0 dB or automated, arrives as a track of its own, so the plug-ins run after the fader as in Pro Tools. Keep the master fader on REAPER's master, in Settings, turns this off
Faders, pan knobs and mute buttons follow automation on tracks in Touch and Latch, as on tracks in Read
Keep frozen tracks frozen, in Settings: a track frozen in Pro Tools arrives frozen in REAPER and plays what Pro Tools rendered
Dragged and preset fade shapes are carried as a volume envelope on the item. Use REAPER fades only, in Settings, writes ordinary REAPER fades instead
After an update, every queued session is checked again
A light by Help shows when a newer version of mollusk is available

mollusk 1.0.1

Fixed

Automated pans arrived on the opposite side in REAPER. Static pans were not affected. Reconvert a session with pan automation to pick this up

New

Ctrl+I adds sessions to the queue from a file window, and Ctrl+Shift+I adds every session in a folder (Command on a Mac)
In REAPER's mixer, faders, pan knobs and mute buttons now follow a track's automation on tracks in Read, as in Pro Tools. Reconvert a session with automation to pick this up
Copy media into project (was Copy audio) also copies the video in the session's Video Files folder
Avid plug-ins that arrive as REAPER's own plug-ins are now named for the plug-in they replace, for example EQ3 7-Band (ReaEQ)

mollusk 1.0

New

Converts a Pro Tools session to a REAPER project: tracks, audio, MIDI, routing, sends, the mix, automation and playlists
Carries the settings inside plug-ins across wherever REAPER has the same plug-in
Swaps Avid's EQ3, Dyn3 and Channel Strip for REAPER's own EQ and dynamics, and names the rest of Avid's plug-ins
Every queued session is checked in the background, so a session with something that will not transfer turns yellow before converting; Refresh queue checks the queue again
A Filter box above the queue finds a session by name
Settings for each session, saved presets, and Duplicate for converting one session several ways
A report beside every project names anything that did not come across
Preferences > Text size makes everything in mollusk 125% or 150% larger
