What's New in v1.4.2

• 📊 New resource meter in the top bar: you can now see CPU and memory usage at a glance while you work, so you can tell when a large session starts to push your machine.
• 🎧 Fixed pitch when switching audio devices: if you used or alternated between devices with different sample rates (e.g. headphones at 44.1 kHz and others at 48 kHz), playback could sound sped up or lower in pitch. It now plays back correctly in every case.
• 🗣️ Fixed the voice guide when switching devices: moving to a device with a different sample rate (common with ASIO) made the count-in and section names land early or late against the bar. They now stay on the beat after the change.
• 🔈 Fixed the "system default" device: selecting it was ignored and you had to pick the concrete device by hand. It now switches to the OS default correctly.
• 🌐 The downloads page now lists every version: the latest one shows by default, but you can pick any earlier version and grab its installers without leaving the site.

What's New in v1.4.1

• 🎧 New block-based audio processing: LibreTracks prepares and stores audio more efficiently for large sessions. The first run after updating may take longer for some files because the cache is regenerated; after that it is saved and future opens are faster.
• ▶️ Importing and editing during playback is much more stable: you can drag audio, .ltpkg packages, move clips, or change structure without forcing playback to reload the whole session.
• 🌊 Waveforms and cache in a single pass: the app reuses the audio engine's work to generate waveforms and avoids duplicate decoding during import.
• 🧲 Safer region editing: resizing a region now snaps better to the clips it contains and avoids shrinking the region past its content.
• 🔊 Fewer clicks and dropouts during live changes: mute, solo, gain, pan, warp, and transport changes are published more cleanly while audio keeps running.
• 🪟 More reliable Windows installation: the installer and native DLLs no longer depend on the Visual C++ Redistributable, avoiding the VCRUNTIME140_1.dll error on clean machines.

What's New in v1.4.0

• 🌊 New way of generating audio waveforms: we now use the app's native decoder, the same one that plays the sound. It's more accurate and fixes waveforms that previously came out short or incomplete on some MP3s. Because of this change, the first time you open your songs some waveforms may be regenerated and take a little longer than usual; it's a one-time thing and they get cached afterwards.
• ⏳ "Preparing audio" indicator: when you open a song or start playback you'll see a real progress bar while the audio gets ready, instead of being left wondering what's happening.
• 🚀 Faster audio import with no needless copies: dragging files from the library onto the timeline creates the tracks and clips in a single batch, and files are no longer duplicated on import.
• 🩹 Clearer drag and drop: audio you're importing shows its status ("preparing", "importing") with translated labels while it finishes loading.
• 🔊 More stable playback on Windows: fixed sound speed drift with the DirectSound and MME drivers, and the audio device is no longer reopened every time you open Settings.
• 🏷️ More legible markers: section, tempo and time-signature flags no longer get clipped or distorted when they sit against the right edge of the timeline, and the timeline header is slightly taller so they show in full.
• ⚙️ Settings without jumps: the Settings window keeps a fixed height so the content doesn't jump as you move between sections.

What's New in v1.3.0

• 🎙️ Automatic voice guides: a voice announces the upcoming section ("Chorus", "Verse 2", "Bridge") and counts you in before each marker or scheduled jump, the way the Playback app does, so the band lands together on the downbeat. Bundled voice pack in Spanish and English, with its own audio output and a count that follows the song's time signature.
• 🎛️ Timeline automation: an automation track where you place cues that fire actions at an exact point — jumps to a section/region, track mute/solo, volume and pan changes with smoothing, applying a mix scene, or waiting a few seconds. Each cue can chain several actions and repeat a limited number of times.
• 🎚️ Mix scenes: save per-track volume, pan, mute and solo combinations and apply them instantly from an automation to reshape the mix at a point in the song.
• 🔍 Interface zoom and fit-to-screen: zoom the whole interface in or out and fit it to small displays, so LibreTracks stays comfortable on laptops and smaller monitors.
• 🎯 Follow the playhead: the timeline follows the playhead during playback, with settings to fine-tune how and when it scrolls the view.
• 🍎 More reliable macOS launch: fixed startup crashes caused by FFmpeg, now bundled inside the app, with compatibility back to Catalina (10.15).

What's New in v1.2.0

• ⚡ Much faster project opening: audio is prepared in parallel and waveforms load lazily, so projects open sooner and with clearer progress feedback.
• ✋ Improved drag and drop: you can now move clips vertically between tracks (with target validation), and the Library shows guide lanes and localized hints while you drag.
• 🎚️ New Vamp and song controls in the transport bar, grouped into clearer button groups with a more polished design on the remote web.
• 📤 Export songs with options: when exporting you can choose whether to include the audio, to share lightweight or complete projects as needed.
• 🎛️ Ableton-style single-line track headers and an active-song filter in the mixer to keep your focus on what you're working on.
• 🗂️ Decoding cache management from Settings: review and clear the cache to free up space whenever you need.
• 🎵 FLAC file support: you can now import and play FLAC audio directly, alongside the formats already supported.
• 🍎 macOS High Sierra (10.13) compatibility: LibreTracks launches again on older Macs.
• 🔤 Bundled fonts: icons and typography render correctly even offline or on older macOS, with no dependency on external fonts.

What's New in v1.1.0

• 🍎 No more freezes on macOS: importing audio into the Library no longer locks up the app while files are decoded. The file dialog opens and the heavy work runs in the background, just like opening, creating, or saving projects already did.
• 🥁 Richer metronome: you can now set the accent on the first beat and choose subdivisions (eighths, triplets, etc.) for more precise practice.
• 🩺 Diagnostics panel and error logging: if something goes wrong, the app keeps a dedicated log you can open to review or share the issue, making support easier.
• 📊 Unified mix meters: tracks now use a single, consistent meter component across the whole UI, with a more stable readout.
• 🛠️ Internal stability and maintainability improvements, plus macOS build fixes.

What's New in v1.0.0

• Per-region warp: every song region now has its own Warp toggle and source BPM. Turn it on from the transport bar and the song time-stretches to the timeline tempo while keeping pitch unchanged, powered by the audio engine's time-stretcher. Right-click a region to fix the source BPM without re-toggling warp.
• Smarter pitch handling: with warp off, transpose works as varispeed (pitch and speed move together, the grid stays consistent); with warp on, pitch shifts but length is fixed to the warp ratio. The full interaction between warp, transpose, and the per-track T toggle is documented on the website (Pitch, Warp & The T Button).
• Multi-select and group drag for clips: Ctrl/Cmd+click adds or removes clips from the selection, Shift+click selects a range, and dragging any selected clip moves the whole group while preserving relative spacing. Plain-clicking an already selected clip collapses the selection on release, like in Ableton.
• Ctrl-drag magnets: hold Ctrl or Cmd while dragging a clip and its edges snap to the playhead, section markers, region edges, and edges of other clips. A vertical gold guide shows you exactly which anchor the clip locked onto.
• Ableton-style timeline navigation: scroll moves vertically, Shift+scroll pans horizontally, Ctrl+wheel or pinch zooms toward the cursor, and Alt+wheel resizes track height. The old scheme is still available as "LibreTracks classic" in Settings.
• Faster loading and editing of large sessions: adding or removing tracks in big projects drops from ~2 seconds to nearly instant because waveforms are no longer re-sent on every change, and the remote control only receives the data it actually needs. The timeline also prevents negative positions and lets you right-click empty space to add an audio or folder track.
• Better project file handling: the save dialog now validates the path and extension before writing, avoiding errors when saving to different locations.
• Clearer large-session timeline: clips and tracks can now be color-coded from the context menu, color can be applied to multiple selected tracks at once, and folder tracks carry that visual identity down to their children so desktop and remote stay easier to scan.
• More comfortable navigation and mixing: scroll moves vertically, Shift+scroll pans horizontally, Ctrl+wheel or pinch zooms toward the cursor, and Ctrl+wheel over the timeline changes track height so you can jump between compact and detailed layouts. The old scheme is still available as "LibreTracks classic" in Settings.
• Better routing and remote control: child tracks can stay on "Inherit" so they follow the folder output automatically, which makes cue/click buses faster to set up. The remote mixer also gets meters, smoother volume/pan interaction, and a more stable transport readout.
• Faster loading and editing of large sessions: adding or removing tracks in big projects drops from ~2 seconds to nearly instant because waveforms are no longer re-sent on every change, and the timeline also prevents negative positions and lets you right-click empty space to add an audio or folder track.
• New Session-style Compact View: press Tab or the view-toggle icon to switch between the linear DAW timeline and a projection that shows one column per song. Each column has its own master fader with meter, effective BPM, play button, and a context menu to rename, change BPM, export, and delete the song. A shared horizontal mixer with M/S/T, vertical fader and pan lives at the bottom. Changes in either view appear instantly in the other.
• Songs are now the primary object of a project: clips always live inside one song and can't cross its end, so you can reorder, export or delete songs as a unit. Deleting a song removes its clips and tempo markers, and prunes auto-created tracks that go empty. Creating a new song pins a tempo marker at its start so it doesn't inherit the previous song's tempo.
• Audio drag-and-drop in the compact view: drag files from the OS file explorer or from the Library onto a song column and one clip per file is created with a matching track. You'll see dashed teal placeholders showing where they will land. Auto-created tracks remove themselves the moment they lose their last clip, so you don't end up with residual lanes.
• Import and export songs as .ltpkg packages from the compact view: use the "Import .ltpkg" button or drag the file from the file explorer onto any part of the strip and you'll see a ghost column previewing where it will land. The imported song is appended at the end of the project with its BPM, markers, clips and tracks intact.
• Multi-select track reordering in the compact mixer: Ctrl+click adds or removes tracks from the selection and Shift+click selects ranges. Drag any selected track and they all move together. Vertical teal lines show you whether you're dropping before or after the target strip; if the target is a folder and you drop in the middle, the tracks become children of that folder.
• Click a song header in the compact view to select it: the border lights up teal and the top toolbar's Transposition and Warp groups bind to that song automatically. The playhead is now visually distinct with a pulsing amber bar on the left so it doesn't get confused with the selection signal.
• Toolbar improvements: the Snap to Grid icon is now a magnet to tell it apart from the view-toggle icon. The Master control auto-hides in the compact view because each song column already has one. The BPM input no longer shows endless decimals during varispeed: it's rounded to 2 decimals without losing precision when you type.
• "Active song only" filter in the compact view: a new funnel button in the top toolbar (visible only in compact) hides the tracks that aren't playing in the song under the playhead, while keeping ancestor folders visible so the hierarchy doesn't break. Handy in big sessions to focus on the faders that actually matter right now. The filter state persists across sessions.
• Move entire songs in the DAW view: drag the amber name band of a song to translate it across the timeline. The region, clips, tempo markers, section markers and time-signature markers all move together in a single atomic operation. With Snap to Grid on the song's start snaps to the nearest downbeat; hold Shift during the drag to bypass snap. If the destination would overlap another song the move is rejected with a clear message and nothing is lost.
• Quality of life: the status banner in the bottom-right corner auto-hides after about 5 seconds. The expanded/collapsed state of Library folders is preserved across sessions so you don't have to close them again every time you open the panel. Clips in the compact view inherit the colour of their track for at-a-glance identification. Importing a .ltpkg no longer fails when the package contains clips that extended past the original end of their region.

What's New in v0.0.9

• In-app update notifications: on startup LibreTracks checks for a newer release and shows the changelog in the active app language, with shortcuts to download, snooze, or skip the version. A manual "Check for updates" button is also available in Settings - General.
• More output channels and a smoother selection flow: hardware output now supports more channels generically, with an Apply/Discard flow that avoids unnecessary device reopens. Bulk channel selection is faster and the track routing picker uses a scrollable combobox for long device lists.
• Faster, lighter project loading: the audio engine reuses the PCM cache across sessions when the source file is unchanged, streams native-format files in place without going through the PCM cache when possible, keeps the cache outside %TEMP% with an LRU size cap, and grows the default budget up to 10% of free disk (minimum 4 GiB). Importing and opening large projects feels noticeably snappier.
• Peak hold on track meters: track meters now keep the latest peak visible for a moment, both on desktop and on the remote, so brief peaks are easier to spot.
• Tap tempo in the transport: the base BPM can be set by tapping the pulse directly from the top bar.
• Better browser integration and website polish: in-app links open the system browser through tightened permissions; the downloads page includes an optional Ko-fi support section.

What's New in v0.0.8

• Large-session playback is now disk-backed: the engine no longer relies on keeping every decoded source fully in RAM and uses a disk cache with read-ahead blocks instead.
• Clearer project loading: opening projects and importing packages now emits progress with prepared sources, RAM usage, and disk-cache usage.
• More reliable live transport: prearmed jump preparation, playhead re-anchoring, and seek fades were tightened to reduce dropouts during live control.
• Faster UI after mutations: operations that do not change audio can skip the full waveform payload and reuse the frontend waveform cache.
• New validation tools: benchmarks and tests were added for streaming, jumps, realtime mixer controls, fades, JSON commands, and voice preparation.
• Expanded release pipeline: release builds now validate macOS bundles, link native dynamic libraries, and publish download counters on the website.

What's New in v0.0.7

• New C++ audio engine: LibreTracks moves away from the previous engine and introduces an optimized native foundation for heavier sessions.
• Pitch backend migrated to Bungee: realtime pitch changes are more efficient and reduce load when playing multiple transposed regions.
• Smoother playback and jumps: voice preparation, prearmed jumps, and playhead synchronization have been tuned for better live response.
• More flexible regions: song and region sizing can now be adjusted more precisely while preparing a project.
• Faster interface: timeline and control optimizations reduce unnecessary work while editing and mixing.

What's New in v0.0.6

• New transpose controls in the timeline: you can now adjust pitch per region and enable or disable transposition per track without leaving the transport view.
• Expanded live control workflow: the mobile remote and MIDI Learn now cover region selection and transpose changes for faster operation in rehearsal or on stage.
• More flexible library handling: you can import audio or song packages with drag and drop on the timeline.
• Clearer audio settings: configuration now lets you refresh devices and fine-tune sample rate and buffer size more directly.
• More stable playback during demanding actions such as jumps, pitch changes, seeks, and in-session imports.

What's New in v0.0.5

• Added compatibility with Intel MacOS

What's New in v0.0.4

• New website and download page: the project now ships with a public site, documentation, screenshots, and release downloads. (Under construction https://libretracks.pages.dev/)
• Audio routing controls: choose where each track plays, and route metronome output to Master or an external device.
• MIDI Learn for live jump actions: map notes or CC messages to jump controls and keep them saved with your app settings.
• Missing-file recovery: the app now flags missing media and helps you locate and relink the files from the library or transport view.
• Playback and input polish: smoother stop/declick behavior, better transport stability, and BPM values are now kept within a safe range.
