v2.0.0-alpha.3
a6ac580
Added
Native VST3 plugin hosting replacing the JUCE wrapper, with
resizable embedded editor windows featuring a header strip, bypass
and A/B state comparison
Durable preset selection with VST3 program tracking, a prev/next
preset selector in plugin windows, and a searchable preset browser
with group filtering and keyboard auditioning
Parameter groups (e.g. VST3 units) shown as sections in the
generic plugin parameter editor
Diagnostics row in plugin windows showing DSP load and latency
(#4526)
Host transport (play state, tempo, time signature and musical
position) delivered to VST3 and CLAP plugins, so tempo-synced
plugins follow the project
Parallel polyphonic voice rendering for bundled synths on a
realtime-safe worker pool, and hosting of the CLAP thread-pool
extension for plugins that parallelize their processing
Drag and wheel scrubbing on the transport bar BPM, time signature
and position readouts (Shift/Ctrl for fine steps)
Pinned-cursor dragging with Shift fine mode for knobs, faders and
balance controls, so values can be edited indefinitely without the
cursor hitting screen edges
Type and format filters with persisted search in the plugin browser
Per-stage progress reporting for project load and save, and a
modal dialog that blocks concurrent project loads
System information and a Copy System Info button in the About
dialog
Windows on ARM installers built as ARM64EC, running natively while
loading x64 plugins in-process
Changed
Multi-channel audio routing reworked around speaker arrangements:
audio folds between layouts per ITU-R BS.775 instead of silencing
unmatched buses, port connections carry explicit channel routings,
and plugin bus changes at runtime detach and revive ports without
losing connections
Sidechain buses are excluded from automatic track chain wiring and
connect through explicit user connections
The playhead keeps its musical position across tempo changes, and
engine-internal pauses (e.g. for undo) no longer trigger
return-to-cue moves
Fixed
Plugin parameters being zeroed on the first processing cycle,
resetting patches of plugins like Surge XT
Crash when removing a MIDI device while its processor is part of
the processing graph (#5284)
Backups cloning their pool files over the main project's pool
files (reversed copy direction in the reflink path)
Crash on port connections referencing nonexistent endpoints; such
connections are now dropped with a warning at load
Data races between the main and audio threads on transport state
and playhead processing state (ThreadSanitizer)
Deadlocks when graph recalculation or engine pausing was requested
while already in progress
Count-in metronome clicks continuing to play after pausing during
the count-in
Faders and balance controls resetting to hardcoded values instead
of the parameter default, and the fader hover label showing
-2.1 dB at unity gain (#5307)
Faders ramping to new volumes faster than real time during
playback
Generic plugin editor windows opening without a title bar on
Windows
Unstyled platform scrollbars and fallback controls on Windows
(#5312)
Arrangers setting drag cursors when the pointer is elsewhere in
the window
Missing icon error in the track inspector's MIDI input expander
DSP load indicator rendering an empty meter as a solid block
Removed
Carla plugin hosting support (already disabled)

v2.0.0-alpha.2
Added
Chord pad panel with preset/scale support, polyphonic audition and
undoable editing (#5169)
Chord editor for placing and editing chord objects in progressions
(#5169)
Chord suggestion engine that recommends next chords based on the
current chord and scale
Chord symbols displayed inside chord clips on the timeline
Chord track recording, including from chord pad notes (#5281)
Musical mode: time-stretch audio clips to follow the project tempo
(offline Rubberband), toggleable globally and per clip (#4368)
Source BPM detection from audio file metadata, with automatic tempo
estimation when metadata is missing (#4746)
Pencil tool for creating objects; hold Ctrl and drag to paint
consecutive objects (#5178)
Eraser tool for deleting objects by clicking or dragging a rectangle
(also via right-drag) (#5180)
Cut tool for splitting objects at the clicked position (Alt+click)
(#5179)
Ramp tool for drawing linear velocity ramps across MIDI notes (#5181)
Audition tool for playing from the clicked position while held
(#5182)
Editable base tempo and base time signature anchored at the start of
the timeline
BPM cell in the transport bar showing the tempo at the playhead,
editable via an undoable dialog
Tempo automation curve drawn behind tempo objects
Draggable clip-start, loop-start and loop-end markers on the clip
editor ruler
Undo/Redo actions in the Edit menu showing the next action name
Panel toggle buttons in the toolbar and View menu
Generic parameter editor window for plugins without a native UI
Open .zpj project files from file managers or the command line
(#5275)
MIDI note activity highlighting on piano roll keys
Undoable velocity editing with per-note clamping and live value labels
Alternating bar shading in the arranger background
Language menu with per-language completion percentages and a "More
Languages" submenu
Optional Tracy profiler integration
Changed
Rename "regions" to "clips" throughout the UI and project format
(#4368)
Reimplement bundled Faust plugins as internal plugins instead of
generated VST3/CLAP bundles
Switch most dependency management from CPM to Conan
Rebuild the live waveform, spectrum analyzer and meter displays on a
new real-time-safe port observation system
Rework automation rendering with a C++ canvas painter and
segment-based curve evaluation on the audio thread
Arranger drags and resizes now preview in place and commit as a
single undo step on release
Default to dark mode on startup
Update translations (Spanish, Ukrainian, Chinese Simplified, German,
Russian, French, Japanese and more)
Fixed
Faders, knobs and balance controls getting stuck when a parent
scroll view takes over the drag (#5308)
Crash from wrapped 32-bit MIDI timestamps after ~50 days of system
uptime (Linux ALSA)
Track name field keeping stale text and staying in edit mode when
switching tracks (#5220)
Deleting or cloning tempo and time signature objects failing
Incorrect note-offs with overlapping same-pitch MIDI notes (#5279)
Distorted automation curves when tempo changes occur within a clip
Track selection pointing at the wrong track when tracks are hidden
Selections of non-moved tracks being lost when moving tracks
Stale entries for deleted plugin files shown in the plugin browser
Failed plugin instantiation leaving broken tracks; an error dialog is
now shown instead
Load/save dialogs not defaulting to the configured new-project
directory (#5211)
Dock panels resizing smaller than their content, and the bottom dock
being cut off on first load
Peak meter and fader value labels shifting the layout as values
change
Removed
Legacy GTK-era code (widgets, actions, event manager, gschema
generator)
Legacy real-time audio stretcher (superseded by the offline
time-stretch engine)
