# 0.1.0 Development Release Notes
|
||
|
||
This remains a development prototype, not a production-qualified DAW. The local
|
||
release workflow is complete without bumping the application version, creating a
|
||
tag or publishing artifacts. The exact source archive SHA-256 and reviewed Git
|
||
commit identify a build; version 0.1.0 alone does not identify all of the
|
||
development revisions that used that version.
|
||
|
||
---
|
||
|
||
## Included Functionality
|
||
|
||
The C99 engine provides bounded graphs, immutable plan publication, stereo
|
||
audio, MIDI instruments and controller bindings, track/bus mixing, automation
|
||
and inline MIDI editing. The C++17 FLTK application adds arrangement, routing,
|
||
recording, undo/redo and a generic LADSPA editor. JACK is the only live
|
||
audio/MIDI backend; core validation and offline rendering work without it.
|
||
Native/LADSPA processors are trusted in-process code. No proprietary energyXT
|
||
resources are included.
|
||
|
||
Project format v13 reads versions 1–13 transactionally. Syntax diagnostics
|
||
identify records and lines. `xtc-check --inspect` lists dependency paths without
|
||
executing plugins. Timing/CPU/RSS reports, repeatable stress runs and virtual
|
||
endurance are available. Configurable install directories, shared install/remove
|
||
inventory, installed MIDI examples and source archive checksum sidecars are also
|
||
included.
|
||
|
||

|
||
|
||
## Upgrading and Removal
|
||
|
||
Back up documents and external media before upgrading. Opening an older project
|
||
does not rewrite it; saving upgrades it to v12, which older readers may reject.
|
||
Use Save As for a separate migrated copy. Moving a project folder preserves
|
||
media stored inside it via relative references. Absolute media and plugin module
|
||
paths must be restored separately. There is no bundled plugin/media migration or
|
||
saved JACK port configuration. See PROJECT_FORMAT.md and RECOVERY.md for exact
|
||
policies.
|
||
|
||
Install to the same layout to repair owned files. Only documented owned
|
||
filenames are replaced; unrelated files with other names remain. Use the same
|
||
source version and directory variables for uninstall. It removes owned files and
|
||
empty owned directories, never recordings or recursively deleting a prefix. A
|
||
changed layout or an older release with a different inventory may require
|
||
removing that old version before installing the new one. No
|
||
database/package-manager registration or automatic cleanup of historical
|
||
inventories is performed.
|
||

|
||
|
||
## Known Qualification Limits
|
||
|
||
Physical devices, multi-hour wall-clock endurance, power-cut behavior and other
|
||
Linux distributions remain unqualified. There is no disk streaming, crash
|
||
autosave, plugin sandbox, latency compensation or stable shared-library ABI. A
|
||
trusted plugin can allocate, block or crash the process. Metadata inspection
|
||
checks file availability only. See KNOWN_LIMITATIONS.md for the complete list.
|
||
|
||
The retained graph performance gate has a documented small-case timing alert on
|
||
the shared development host; the project timing comparison passed. This alert
|
||
was not hidden by changing the baseline. See PERFORMANCE.md before using these
|
||
measurements as latency expectations. Sanitizers and virtual endurance qualify
|
||
software paths, not hardware timing.
|
||
|
||
Default-configuration CLAP/VST2/VST3 mono effect loaders, common GUI
|
||
discovery/insertion/replacement and v11 format identity are supported. Pinned
|
||
MIT CLAP and BSD-3-Clause VST3 C headers ship with notices; VST2 uses original
|
||
compatibility declarations. Modern instruments, parameters/state/editors and
|
||
multichannel layouts remain unsupported. No third-party modern plugin has been
|
||
qualified.
|
||
|
||
CLAP/VST2/VST3 mono instruments are supported, bound to MIDI tracks, with
|
||
sample-offset notes, a saved live target, track mixing, GUI assignment/undo and
|
||
v12 persistence. See PLUGIN_HOSTING.md for compatibility and controller/state
|
||
limits.
|
||
|
||
A flat DAW workspace, shared dark theme, track-creation sidebar, read-only
|
||
musical transport/track inspector, colored track clips and real MIDI previews
|
||
are included. New MIDI/audio track commands are undoable and prepare candidates
|
||
before adoption. The default window is 1280 × 800, minimum 1220 × 720. No
|
||
dependency or project-format change. See WORKSPACE.md and the new
|
||
`modern-session.xtc` example; existing engine/plugin limitations still apply.
|
||
|
||
A sequencer grid/Snap dropdown, absolute grid snapping for moves and trims, MIDI
|
||
double-click editing, a piano velocity lane/slider and per-track instrument
|
||
dropdowns are included. Snap preferences are UI state; velocity and instrument
|
||
bindings use the existing v12 format. No new dependency or engine feature is
|
||
required. See WORKSPACE.md for supported divisions, controller semantics and
|
||
limits.
|
||
|
||
Edit / Preferences provides an Apply button and `~/.xtc.conf` INI persistence,
|
||
configurable plugin search paths and a file library, plus sequencer ruler loop
|
||
selection and sample-boundary playback wrapping. See PREFERENCES.md for
|
||
settings, reconnect behavior and looping limits.
|
||
|
||
The single-track mixer panel is replaced by a scrolling studio mixer: vertical
|
||
dB faders, flat pan knobs, mute/solo, routing and stereo meters on every track
|
||
and bus, plus a pinned master monitor. Selected-track automation remains below
|
||
the strips. No project format or engine changes. Screenshots are refreshed; see
|
||
MIXER.md and screenshots/README.md.
|
||
|
||
Searchable Commands (Ctrl+P), editable project BPM, a live track inspector,
|
||
session statistics, Fit song and an optional persistent Follow playhead control
|
||
are included. Numeric input remains intact during display refreshes. Screenshots
|
||
are refreshed, including the command palette. See WORKSPACE.md.
|
||
|
||
Dependency-free Soft Keys/Sub Bass instruments and Delay/Reverb effects are
|
||
included, with saved controls and automation. Choose instruments in track
|
||
headers; insert effects on selected graph wires from Edit. See
|
||
[BUILTIN_DEVICES.md](BUILTIN_DEVICES.md).
|
||

|
||
|
||
## Audio Source Editing
|
||
|
||
Audio clips now open a modal waveform editor with native frame selection, zoom,
|
||
source statistics, nondestructive timeline trims, selection export and save-copy
|
||
adoption. Local one-step undo supports reverse, polarity inversion, DC removal,
|
||
linear/equal-power fades and gain/normalization. Silence boundaries,
|
||
zero-crossing snapping and amplitude attack markers support transactional clip
|
||
slicing. Originals are never overwritten; exported media remains available to
|
||
project undo/redo. Source editing uses the existing mono downmix and bounded
|
||
snapshots; timeline cuts round to musical ticks. See
|
||
[AUDIO_EDITOR.md](AUDIO_EDITOR.md) for exact behavior and remaining limits.
