Changelog

v1.7.14 New

• In-app Support Center. You can now report a bug or request a feature right inside the app — no email needed. The new Support tab lets you open a ticket, pick a category, auto-fills your session details, attaches the source session in one click, and tracks each ticket (with an ID and status) plus our replies right in the app.
• Folder tracks — fully bidirectional, all formats. Pro Tools basic folders, Cubase/Nuendo folder tracks, and Reaper folders now convert both ways across Pro Tools, Reaper, Cubase and Nuendo — preserving nesting, open/closed state, and folder solo & mute.
• Colour fidelity. Track colours now carry across correctly — including folder-track colours and Pro Tools' default per-type track colours (audio, aux, master, and the rest) — so a converted session looks like the original in Cubase and Nuendo instead of grey.
• Bar offset (Song Start). Bar/beat display offsets now convert between Pro Tools, Cubase and Nuendo.
• Fixes. Fixed a launch crash on macOS 14.x; "invalid fade" errors and empty clip lists on high-sample-rate (96 kHz) Pro Tools sessions; empty waveforms in standalone Reaper (linked audio no longer gets a stray numeric suffix); a fully-lowered fader (−∞ dB) no longer converting to maximum gain; and numerous Cubase/Nuendo fidelity fixes (track order, mute state, instrument tracks, per-channel clip handling).

v1.7.13 New

• More reliable Pro Tools ↔ Nuendo / Cubase conversion. Fixed sessions that could fail to open in Nuendo ("created with Cubase 10.0.50") — they now open correctly. Fixed conversions with routing and panning that could stop with a "child count" error — sessions with playlists and offline media now convert cleanly. The active playlist (comp version) of a track is now correctly preserved — no more empty active Track Versions after conversion.
• Media & offline sessions. Sessions referencing audio on disconnected drives now convert without failing; the media stays linked for you to relink in the target DAW. Better source-file identity, so media re-links correctly after glue / rename round-trips.
• MIDI carried across formats more faithfully. Notes, controllers, SysEx and Poly Pressure preserved, with clear diagnostics where a target can't represent something. Shared / linked MIDI parts and Track Versions handled more accurately. Nuendo 15 (RIF2) MIDI reading fixed, including musical timing.
• Musical timing, markers & tempo. Tempo ramps and musical markers preserved across formats. Marker and clip timebase (musical vs. linear) kept where the target supports it. Range / selection markers carried through where possible.
• Tracks. VCA and Sampler tracks are no longer silently lost — they're carried through with a clear, named downgrade where the target DAW has no equivalent (a Sampler becomes an Instrument track keeping its MIDI). Unsupported track types now show a clear message instead of being silently turned into audio.
• Video. Four-format video handling expanded; mixed audio + video Reaper tracks split cleanly into separate Video and Audio tracks.
• Preflight & stability. A clearer, calmer preflight report (Automatic / Compatibility / Must-fix) replaces the old generic error dialog. Missing or offline media never blocks conversion. Reaper extensions now correctly find the app after the Interchanger rename (fixes "PT Reaper Converter not found").

v1.7.12 New

• MIDI between Pro Tools and Cubase / Nuendo now round-trips cleanly. MIDI playlists and Track Versions transfer in both directions — each track keeps its own versions in the version selector, with no more version cross-mixing and no floating "Lane N" tracks. Notes are present in every version's clips (alternate playlists no longer come through empty). Instrument tracks stay Instrument tracks in Cubase/Nuendo (they were arriving as plain MIDI tracks). And the false "Missing Track Version" dialog on opening a converted session is gone.
• Crossfades in Cubase / Nuendo now draw at every clip junction with correct equal-power geometry and crossover point.
• Other fixes: MIDI clip lengths are exact (no more clips stretching to infinity); stereo ReaSurroundPan — the right channel's front/rear now mirrors the left correctly; and improved hidden / inactive track handling across formats.
• Known limitation, coming next: track colour on folder-nested Instrument tracks does not yet transfer.

v1.7.11 Bug Fix

• Cubase / Nuendo Group channels now become Reaper folders (and back). Converting a Cubase/Nuendo project to Reaper nests the tracks routed to a Group inside a Reaper folder, preserving the group structure; a Group-into-Group chain becomes nested folders.
• MIDI track colour now transfers to Cubase and Nuendo — mapped through the project's Event Colors palette, like audio tracks and clips.
• Fixed clip gain on offset clips → Cubase/Nuendo. A clip taken from partway into its source file, carrying clip-gain automation, could fail to convert to Cubase/Nuendo with a "gain envelope point outside the clip window" error (or, in milder cases, place the gain slightly off). Clip-gain positions are now handled correctly relative to the source file. (Thanks to Corrado for the report.)
• Fixed the "Convert to" button labels. After loading one format and then a different one, the target buttons kept the previous labels while still doing the correct conversion — so a button could read "Cubase" but convert to Reaper. The buttons now always show the correct three target formats for the loaded source.

v1.7.10 Performance

• Fixed a minutes-long hang when reading Reaper projects with large virtual-instrument states. Projects carrying multi-megabyte VSTi state blocks (Omnisphere, Vienna Ensemble Pro, MassiveX, Pigments and similar scoring templates) made the read and conversion appear to hang for many minutes — a 110-track VI template could take 5–10 minutes instead of seconds. The output was always correct; the cause was a quadratic-time string accumulation in the plug-in state decoder, now linear. The same template converts in about 2 seconds. Reported by Dedric Terry (Gearspace) with a reference project — thank you!
• No other changes; everything listed for 1.7.9 applies.

v1.7.9 New

• Track and clip colours now transfer to and from Cubase (.cpr) and Nuendo (.npr). Colours map through the project's Event Colors palette — on write each source colour lands on the nearest palette slot; on read the project's own palette (including customised ones) is decoded, so what you see in Cubase is what arrives in Pro Tools / Reaper. Between Pro Tools and Reaper colours stay full 24-bit RGB as before. Known gap: a MIDI track's colour on the Cubase/Nuendo write side isn't set yet (audio tracks and all clips are) — coming next build.
• Session start timecode now transfers on the Cubase/Nuendo routes, both directions. A Pro Tools or Reaper session starting at 01:00:00:00 opens in Cubase/Nuendo at 01:00:00:00 and back — written into the genuine Project Start Time field of Project Setup (byte-verified against Cubase-saved references). NTSC pull-down rates (23.976 / 29.97 / 29.97 drop / 59.94) are handled correctly: Cubase stores start time scaled by 1.001 at these rates and Interchanger applies the same law both ways, so timecode matches frame-exactly instead of drifting 0.1%.
• Under the hood: project frame rate is carried into written .cpr/.npr headers (fixed late in the 1.7.8 line; included here for completeness).

v1.7.8 — PT-Reaper Converter is now Interchanger Major

• New name, same app. PT-Reaper Converter is now Interchanger — the new name reflects the new scope: four DAW formats instead of two. Your license keys and settings carry over; nothing to re-enter. On first launch the direct-download build offers (never forces) to move the old "PT Reaper Converter.app" to the Trash; your default apps for .ptx / .rpp are not touched.
• New: Cubase (.cpr) and Nuendo (.npr) — read and write. Any of the four formats converts to any other: Pro Tools ↔ Reaper ↔ Cubase ↔ Nuendo. Both the classic RIFF container and the newer 64-bit RIF2 container (Cubase/Nuendo 13+ large projects) are read; written projects use classic RIFF, verified opening in Cubase 10 and Nuendo 15.
• Tracks & mixer structure to/from Cubase & Nuendo: audio tracks up to 7.1.2 (Cubase 10/11 display height as 5.1, data preserved; native from Cubase Pro 12); Cubase Group Channels ↔ PT Routing Folders / summing Auxes ↔ Reaper folder buses; Cubase FX Channels ↔ PT Aux Inputs / Reaper receives; output buses created in Audio Connections at the correct widths; track sends with level / pan / pre-post / on-off into the eight Cubase slots.
• Clips: position, length, source offset, gain (static and envelopes), mute, names; fade-ins/outs and crossfades with their curve shapes, including cross-file crossfades and the crossfade midpoint.
• Surround panner ↔ VST MultiPanner, both directions: channel positions including independently placed L/R channels (through Cubase's own linked-parameter geometry), width / rotation, the three divergences, Center %, LFE level, height (Z) and Height Divergence — static values and automation lanes, and reading a .cpr/.npr panner back out to ReaSurroundPan / the PT panner. Panner values were byte-calibrated against hand-made reference projects.
• MIDI: notes, CC, pitch bend, program change, aftertouch, SysEx, per-track MIDI channel, part mute, shared (ghost) parts. A PT Instrument track arrives as a MIDI track (carrying the virtual instrument itself is on the roadmap).
• Track Versions ↔ playlists: Cubase/Nuendo Track Versions (audio and MIDI) become PT alternate playlists / Reaper fixed item lanes and back; the active version carries the playing content, and clips inside inactive Versions keep their fades, crossfades, mute and gain envelopes too.
• Timeline & video: markers, the full tempo map, time-signature changes and frame rate; the video track with its clips (Cubase/Nuendo play one video track — extras reported and skipped). Same media pipeline as the other directions: split-mono merged to interleaved WAV, FLAC / OGG / MP3 / WavPack / M4A / AAC / AIFF decoded, sample-rate mismatches resampled.
• UI: input accepts all four formats with auto-detection and a new Convert to selector; preflight warnings now appear before converting and re-evaluate when you switch target; session info shown for every input format and no longer disappears after a conversion; new app icon.
• Fixes: demo mode now clamps video and MIDI clips to the 2-minute window on the Cubase/Nuendo routes too; the updater no longer offers a "downgrade" when you run a build newer than the server's; bug-report emails and output-folder names follow the selected target format.
• Honest limitations: plug-ins and plug-in automation don't transfer yet in any direction (only ReaSurroundPan is interpreted, as a panner) — planned next; PT folder tracks into Cubase/Nuendo are skipped with a warning (Group routing is preserved); a PT Instrument track's virtual instrument doesn't transfer yet (MIDI does); sends wider than the destination bus are dropped with a warning.

v1.7.7 New

• A large stability and fidelity pass over v1.7.6 — routing, panning, sends, track colours, MIDI and fades all convert more faithfully in both directions.
• Routing & buses (Reaper → Pro Tools): parallel hardware feeds become proper Pro Tools multi-assign outputs, carrying the original send level, tap point and mute; folder children that feed a channel offset of their parent land on the correct sub-path of the parent bus, at the real channel width; new Hardware Output Buses toggle — when off, hardware buses are emitted as internal buses (no physical binding, no warnings) and the Control Room bus is removed entirely; bus tab order now matches Pro Tools convention — the master chain first, then session order.
• Panning, sends & surround: Reaper track-to-track sends convert to Pro Tools sends A–J (the general AUXRECV case), including send volume, pan and mute automation; stereo width converts to Pro Tools dual pans, and stereo sends get dual pan lanes (a centred balance becomes full stereo L−100 / R+100); surround divergence follows the final Pro Tools panner format, and 5.1.2 sessions read their divergence correctly; numerous pan-automation sign and mirroring fixes in both directions.
• Track colours: the Pro Tools colour model was rebuilt on measured ground truth (empirical 72-slot palette with hue-first matching), so track and clip colours survive the round trip far more accurately.
• Tracks: hidden tracks convert both ways (Reaper Track Manager hidden ↔ Pro Tools hidden); new Skip Hidden and Skip Inactive toggles (replacing the old Skip Muted control) in the Track Data options; converted sessions no longer open in Reaper with every track selected.
• MIDI: MIDI tracks now open in Clips view in Pro Tools; MIDI alternate playlists convert both directions (Reaper fixed lanes ↔ Pro Tools playlists).
• Fades, crossfades & clips: crossfade slope and skew (curvature) are now written to Pro Tools; fade slopes are read as floating-point, so fractional bezier curves are no longer flattened to a straight line; overlapping fades are clamped strictly below the meet point, so Pro Tools no longer drops clips whose fades merely touch.
• Correctness fixes: critical frame-rate fix — 23.976 fps is now written with the correct code (previously mis-tagged); video clips are clamped to their real source duration for both online and offline files; session-start timecode is preserved again (regression fix); the updater no longer offers a "downgrade" when you already run a newer build than the server.

v1.7.6 New

• Reaper sends now convert to Pro Tools sends. Track-to-track sends (receives) become Pro Tools send slots A–J with level, pan, mute and their automation; send destinations become matching buses.
• Hardware output buses with a toggle. Reaper tracks routed straight to hardware outputs become named hardware buses in the Pro Tools I/O Setup. Switch "Hardware Output Buses" off in the Track Data filter to get plain internal buses instead — the session then opens on any machine with no I/O warnings.
• Parent-channel routing becomes sub-paths. A track feeding specific channels of its folder (say 3–4 of a 5.1 bus) now routes to a matching sub-path on the parent bus (C+LFE), with its stereo placement carried into the Pro Tools pan knobs — the LFE-group workflow converts intact.
• Static mixer state arrives exactly as set. Pan knob positions, send levels, send pans and send mutes now show correctly on converted Pro Tools tracks.
• Hidden and inactive tracks. Hidden Pro Tools tracks arrive hidden in Reaper and inactive tracks arrive muted — or skip either kind with the new Skip Hidden / Skip Inactive switches. Hidden Reaper tracks convert hidden to Pro Tools, with a skip switch too.
• Crossfades keep their midpoint. A crossfade with a shifted transition point (skew) now sounds identical after conversion, in both directions, including short crossfades.
• MIDI playlists convert in both directions: Pro Tools alternate playlists become Reaper fixed lanes on MIDI tracks and back.
• Fixes: MIDI tracks no longer open in Blocks view in sessions with a video track; hardware-routed tracks keep their position in the Pro Tools track list; converted sessions no longer open with every track selected.

v1.7.5 New

• Pro Tools tracks routed to physical hardware outputs now convert to matching direct hardware outs in Reaper — console and multi-output monitoring sessions (VENUE and similar) arrive playing exactly as they did in Pro Tools instead of collapsing into a single track.
• An output path carrying a Pro Tools Master Fader becomes a Reaper folder track with the fader's level and volume automation, so the real gain stage survives the conversion.
• Reaper → Pro Tools: comped takes land correctly — the lane you hear in Reaper becomes the main playlist in Pro Tools, with all other lanes as alternate playlists.
• Pooled (ghost) MIDI items are fully supported, long MIDI clips keep their exact length, and a MIDI track keeps its position in the track list.
• Fixed a session-structure bug where a MIDI track in the middle of a session could duplicate one track, hide another and shift clips by one track in Pro Tools.
• Playlist and duplicate track names now use clean Pro Tools style suffixes ("Solo.2" instead of numeric codes).
• The update dialog gained a What's New button linking to this changelog.

v1.7.4 New

• Reaper comping now converts to Pro Tools playlists: fixed item lanes and multiple takes become playlists on the same track — the active lane or take plays on the main playlist, empty named lanes carry over, and takes of mixed channel formats split per format track.
• New Track Data filter for the Reaper → Pro Tools direction: choose whether lanes and takes expand into playlists, plus markers and tempo map. Each direction remembers its own settings.
• Playlist fixes in both directions: same-position clips on different playlists are no longer lost, every clip lands on its own lane, tracks with more than ten playlists attach all of them, and playlist clips always reference their own source files.
• Fixed: in sessions referencing more than 256 audio files, clips of offline files could link to the wrong source and be trimmed on open.
• Fixed: microscopic fade remnants from Reaper edits no longer produce invalid fades.
• Duplicate track and playlist names are renamed for Pro Tools and reported in the preflight; free item positioning tracks with overlapping clips get a clear warning.
• Bars|Beats and time-based markers keep their timebase in both directions (from 1.7.3).

v1.7.3 Bug Fix

• Fixed: a session with two or more markers could fail to open in Pro Tools in v1.7.2. Marker lists of any size open normally again.
• Markers now keep their timebase in both directions. Musical (Bars|Beats) markers convert as tempo-following Bar|Beat memory locations in Pro Tools, and time-locked markers stay absolute — read from each marker itself, not from the ruler display. A session that mixes both kinds is split correctly onto Beats and Time ruler lanes in Reaper, and Pro Tools now shows converted Bars|Beats markers on the right bars.

v1.7.2 Major

• MIDI tracks convert both ways (Reaper ↔ Pro Tools), including sessions that mix audio and MIDI.
• Musical / tempo-locked (tick-based) clips, plus tempo and meter changes, are preserved in both directions.
• Pro Tools markers now import correctly via File → Import → Session Data.
• Fixed the session frame rate being read incorrectly on large-I/O sessions (e.g. big live-console recordings).
• Offline video clips now convert instead of being dropped.
• Clip boundaries land at exact sample positions.
• Removed a false "overlapping items" warning on clips that only share a crossfade.
• Removed a false surround-format warning on valid 7.1.2 / Atmos ReaSurroundPan tracks.
• Fixed sessions that could convert to an empty Reaper project (including some AAF-derived sessions).
• Improved handling of older Pro Tools (2020.x) sessions.
• Exported sessions no longer embed an internal developer path.

v1.7.1 New

• New: "Spot to Pro Tools" Reaper extension. Spot selected Reaper clips straight into a running Pro Tools session at a chosen timecode — match by track name or free placement, create missing PT tracks, link or copy media, overlay or replace existing clips, with a live preflight and auto-bake.
• Video clips now carry their clip colour across to Pro Tools, and the active video track is marked. Courtesy preflight warnings for mute / playrate on video clips.
• Preflight now warns about clips that can't translate losslessly — reversed, phase-inverted, or stretch-marker (time-stretched) — so nothing changes silently.
• Reaper → Pro Tools: looped items expand and convert correctly; clip gain (trim × take volume) preserved; overlapping fades clamped so Pro Tools no longer drops those clips.
• Interleaved WAV merges preserve IEEE float format.
• Playlists: globally-unique names (PT-style ".1" dedup) and faithful layout.

v1.7.0 Major

• Reaper sessions whose audio lives in several different folders, or across different drives (a shared sound library on another drive, a separate rendered or bounced folder, your project media), now relink correctly in Pro Tools. Every file is found by its real path. Files that are offline at conversion time keep their paths too, and any file you relink yourself — on any drive — is written into the converted session.
• Markers now come through with their names and colours, both when converting a session with the app and when importing through the Reaper extension.
• A Reaper master track now becomes a Pro Tools master routing folder, including stereo masters.
• Added a Copy File Name button to the Relink dialog.

v1.6.9 Performance

• Significantly faster conversion on large sessions.
• Pro Tools auto-links Sound Devices and Reaper-rendered WAVs by ID. The converter now preserves the full SMPTE UMID byte-for-byte so PT recognises files from any field recorder vendor.
• Offline RPP → PTX conversions now link by filename automatically. When you convert an RPP without the audio on disk, Pro Tools auto-links files from the Audio Files folder on import — no Relink dialog. Preflight clearly lists which files are offline.
• ReaSurroundPan tracks no longer lose 3 dB on the Pro Tools side. The converter applies a per-track 0 dB pan law override on tracks carrying ReaSurroundPan, so the plugin's panning isn't double-attenuated by the project pan law.
• Large sessions no longer crash on memory exhaustion.
• Preflight no longer freezes the interface on heavy sessions. Analysis runs in the background; the window stays responsive.
• Stereo .L/.R file pairs are no longer misclassified as split-mono.

v1.6.1 Bug Fix

• Pro Tools → Reaper: fixed wrong clip sync position when Pro Tools regions share a name (full-file + trimmed-clip derivative). Clips now play from the correct offset instead of the start of the source file.
• Pro Tools → Reaper: fixed Side-percent automation leaking into Reaper divergence on 7.1.2 buses. Size and Divergence knobs now use their correct per-slot transforms.

v1.6.0 Major

New features

• Output mode tabs. Two clearly labelled modes: Link to source keeps the project as a thin reference to your originals, Copy Media (Standalone) produces a self-contained bundle with audio (and optionally video) copied inside. A "Save in same folder as source" checkbox in Link mode lets you drop a file and convert it next to the original with one click. Session / bundle name auto-fills from the source on every drop.
• Preferences popover. A gear icon in the top-right corner sets the audio + video folder names once — per direction (Pro Tools side typically Audio Files + Video Files, Reaper side typically Media). Settings shared between the standalone app and the Reaper extension automatically.
• Full UI parity in the Reaper extension. The Reaper-side Import dialog now matches the standalone app visually — same Input block with full session info, same Preflight subsections with status icons, same Output mode tabs, same Track Data filter.
• Native Relink dialog inside the Reaper extension. Per-file candidate search, Match-by-Name / File-ID / Duration filters, multi-folder search areas — the extension shells out to the converter app for the exact same Relink UX as standalone.
• Preflight redesign. Two subsections always render: Automatic conversions (split-mono merges, sample-rate resamples, FLAC / MP3 / OGG transcodes) and Compatibility warnings. Each category shows file count + total size, with a green check-mark when clean.
• Per-category preflight popovers. Click any category to see the file list — names, channel counts, formats, source sizes and total processed size.
• Reaper item Channel Mode (CHANMODE) read on RPP → PTX. Items set to Mono Left, Mono channel N, Stereo 1/2 or any Stereo N/N+1 pair now map to Pro Tools' per-clip channel index. No more silent dropping of the channel selection.
• Fade-shape preservation in both directions. Linear, concave, convex and S-curve fades, fade-ins, fade-outs and crossfades carry their audible curvature across the conversion. Earlier builds shipped a generic equal-gain shape regardless of source.
• Reveal-in-Finder. After a successful conversion, the Convert button transforms into "Reveal in Finder".
• Report-a-Bug link. Top-left of both the standalone window and the Reaper extension dialog — opens a prefilled email with diagnostic info.

Surround pan fixes

• Stereo tracks routed through a surround panner (5.1 / 7.1 / 7.1.2) no longer arrive in Reaper with the ReaSurroundPan X puck stuck at center. Both source channels reach the plugin as independent L and R; no per-track Reset click needed.
• Pro Tools' Size knob (7.1.2 only) now converts correctly to Reaper's per-channel Divergence — both mono input and stereo input (independent L / R Size).
• Right-channel Divergence is preserved when Pro Tools authored it independently from the left channel.
• Right-channel Y, divergence and LFE pan slots now map to the matching Reaper parameters (in_2_Y, in_2_divergence, in_2_LFE) instead of dropping to defaults.

Conversion correctness

• Video clips now reliably reach the Reaper RPP from the standalone GUI (previously dropped silently on second-and-later conversions).
• Mono Pro Tools tracks routed to a wider surround bus now have MAINSEND_NCH upgraded to the bus width — every channel of the up-mixed signal reaches the parent.
• Aux tracks that up-mix their input get the same MAINSEND_NCH boost.
• Read-only output folders are caught before conversion starts, instead of failing late inside afconvert.
• The Reaper extension's red close-button no longer freezes the Reaper UI.
• Pre-built RPP files now analyse on a background thread — no UI hitches on large projects.

RPP → PTX

• Reaper item CHANMODE values flow end-to-end: track-format detection, clip wrapping and split-routing all respect them.
• Custom clip names + clip-gain are preserved when the item spans the full source file (previously overwritten with source-file defaults).
• Fade envelopes are clamped to the CHANMODE-narrowed channel count.
• Three previously-silent clip drops on the resample / transcode path no longer happen.

UX polish

• Larger drop zone before an input is selected.
• Output panel hidden until a file is dropped — cleaner first-launch state.
• Volume Automation picker removed — always Direct (1:1). Raise Reaper's fader range in Project Settings if a session exceeds +12 dB.
• Per-file split lists expose the "Folder with clips" auto-split as its own row in the preflight popover.
• User guide gained a "Save Copy In" workflow tip and was translated to Russian.
• User guide gained a "bounce before convert" tip for Reaper-item features the converter can't preserve.

Known limitation

• Session timeline-start timecode is not yet honoured on either side; clips land at whatever raw position the source records. On the wishlist for a future release.

v1.5.6 Bug Fix

• Reaper → Pro Tools: clip gain now survives correctly when several items on the same track share a clip name.

v1.5.5 Bug Fix

• Fade curve shape now survives the round-trip in both directions. Concave, linear and convex slopes for fade-ins, fade-outs and crossfades open in the other DAW exactly as you set them — no more flattening to a generic equal-gain curve.
• Track Data popover: the "Main Pan Automation" toggle no longer says "(up to 5.1)". The 7.1 and 7.1.2 panners shipped in 1.5.2 already converted their automation correctly; the label was just out of date.

v1.5.4 New

• Wider surround formats supported bidirectionally: 7.1 and 7.1.2 (Control Room widen, sub-path routing, Side / Size / heights)
• Static surround pan slider positions now convert from Reaper to Pro Tools (previously only automation lanes converted)
• LFE handling simplified: first channel only, no stereo compensation, in both directions
• Source audio files are never modified by the converter, regardless of output folder location
• Video Link mode: Pro Tools now references video files at their original absolute path, including external drives — no more zero-byte Video Files folder next to the output. Copy mode unchanged
• Non-fast-start MP4 files (moov atom at end of file) now convert correctly — previously the video clip was silently dropped

v1.5.1 Bug Fix

• Reaper → Pro Tools: fixed app freeze when converting projects with a video track. On systems with limited free disk space or RAM, the app could appear to hang for minutes after clicking Convert. The video probe now reads only what it needs from the source file instead of loading the full video into memory.

v1.5.0 Major

• Reaper → Pro Tools (RPP → PTX) — first major release with bidirectional conversion
• Direction is auto-detected from the input file extension
• Audio, Folder and Video tracks (sends-receivers become Pro Tools Aux Inputs)
• Clips: positions, fades, crossfades with shape mapping, names, colors, mute, static and dynamic clip gain
• Folder structure with bus auto-creation, multichannel routing, output bus, surround formats up to 5.1
• ReaSurroundPan support — mono and stereo inputs, independent L/R panners, full XY automation, divergence, LFE, center percentage
• Audio pipeline: FLAC / OGG / MP3 → WAV, sample-rate conversion, split-mono → interleaved consolidation
• Standalone bundling — copies non-conforming files into the session folder
• Pro Tools relinks every audio file correctly across folders, even when output sits in a different directory
• Damaged or non-standard WAV headers repaired automatically
• Video tracks (.mov, .mp4, .avi, .mkv, .m4v, .mxf) — symlinked by default, optional full copy
• Tempo, time signatures, project markers (with names and colors → Memory Locations)
• Preflight report and file relink dialog before conversion
• CLI: --convert, --copyAllAudio, --copyVideo, --routingMode, --options, --preflight
• PTX → RPP stability: 256+ source files no longer trim clips, stable file IDs across runs, surround pan automation including stereo R-channel
• Pro Tools 2025.12+ markers/playlists, Pro Tools 2023.6 source-file index correction
• Trim Overlapping Clips toggle (matches Pro Tools "topmost wins" behavior)
• License manager: Data Protection Keychain, hardware UUID binding, offline grace period
• Update checker, in-app "Report a bug" link
• Performance: 14,550 clips / 174 tracks: 44s → 3.5s

v1.2.0 New

• Playlists — Pro Tools playlists → Reaper Lanes (audio & video)
• Video track with clips
• Clip colors
