#181 already pushes instrument params each block, so drop the duplicate
apply_instrument_params. Import Session Data now brings a Sampler's sample
along and remaps its source id.

JSON has no NaN or infinity, so serde writes them as null, and loading
null into a plugin parameter failed the whole session with "not a
SoundCraft session: invalid type: null, expected f32". One plugin
reporting a non-finite value, or a value like 1e39 that overflows f32
in an edited file (it loads as infinity), made the session and every
later save and autosave of it unopenable.
Insert and instrument parameters that are null or overflow f32 are now
dropped on load, so they keep the plugin's default and the rest of the
session opens.
Audio that exists only in memory (takes, consolidations, AudioSuite
renders, commits) gets the default path `Audio Files/<name>.wav`, and
Save treated an existing file at that path as the source's own and
rewrote it. Names repeat easily: two sessions in one folder both call
their first take on Audio 1 "Audio 1_02", and consolidating twice on
Kick makes two "Kick_consolidated" sources. Saving silently replaced
the earlier audio, so the other session or the earlier clip played the
wrong audio once reopened.
Save As also trusted a same-named file in the target folder for audio
saved elsewhere, so saving into another session's folder could point
the new session at that session's audio.
New audio now goes to the first free name (`<name>.wav`,
`<name>_01.wav`, ...), created with create_new so no existing file is
ever truncated, or to a file that already holds exactly the same bytes,
such as a take saved again after undoing past a save. Saved audio is
reused only when saving into the folder it was saved in, which the
session now remembers, so undoing past a Save As or saving after Save
Copy In can't pick up another session's files either. Audio that
failed to load keeps pointing at its old folder when the session is
saved elsewhere.
A third built-in instrument next to Subtractive Synth and Drum Synth. It plays one
sample across the keyboard: root note, transpose and fine tune, key tracking, key and
velocity ranges, amp ADSR with velocity sensitivity, sample start, forward or ping-pong
loops, gate or one-shot playback, 32 voices with cubic interpolation. The sample's own
rate is converted as it plays.
- dsp: `Plugin::set_sample` and the `SampleSource` trait hand an instrument shared
audio without copying; the Adsr from the synth is reused.
- model: `Insert::sample` names the session source the sampler plays.
- mix: sync hands the pool audio to the instrument when it changes, and built-in
instruments now get their parameter values applied (they always ran on defaults).
- engine: `mix.sampler_load {track?, path, params?}` decodes WAV, AIFF, FLAC, MP3, OGG
(anything file.import_audio reads) into a session source, resampled to the session
rate and saved in Audio Files with the session; `mix.sampler_clear`; and
`mix.instrument_param {track?, param, value}` for any built-in instrument.
Tests generate their audio in code; no bundled assets.
Nothing in the Clip List could be removed: neither its files nor its clips
had a delete action, so everything stayed listed.
- New `clip.clear` (Cmd+Shift+B, the Clip List Clear shortcut in Pro Tools),
also offered as Clear… on every Clip List row's right-click menu. A clip
leaves its track; a file leaves the session with its decoded audio and is
never deleted from disk. One undo step brings everything back.
- As in Pro Tools, Clear asks first. The dialog names what goes, including
the clips on any track or playlist that still play a file being removed:
they are removed too. Programmatic calls never open it; they pass
`with_clips: true` to remove a file still in use, and fail without
changing anything otherwise.
- File rows can be selected now (`edit.select {sources}`, kept in
`EditState::selected_sources`); with no ids, `clip.clear` acts on the
Clip List selection.
- Remove Warp and re-warping ignore a stored original whose file has been
cleared, so they never point a clip at a missing file.
Video (new standalone crate soundcraft-video):
- Pure-Rust H.264 (Baseline/Main/High), ProRes (all flavours) and Motion JPEG decoding with
ISO-BMFF demux, adapted from FilmCraft's crates; fuzzed with mutated/truncated movies
- TrackKind::Video with ClipContent::Video referencing Session.videos; file.import_video adds
the picture track and the movie's audio; relinking on open; video.offset/online/list
- Video and Video Universe windows, thumbnails on the timeline, background decoding
Third-party plugins:
- Plugin state (CLAP state ext, VST3 component + controller state) saved in sessions
- Hosted instances created, state-loaded and dropped on the UI thread, never the audio thread
- Plugin editors: floating CLAP GUIs and VST3 views on macOS (verified with Melodyne)
- New isolated FFI crate soundcraft-au-host: Audio Units on macOS (effects and instruments,
parameters, latency, MIDI, ClassInfo state), wired into the mixer and plugin browser
UI: Window > Renderer (speaker layout with live levels and object positions), Window > UI
Customization (interface scale, reduce motion), Window > Configurations > Auto-Update.
Fix: saturating sample-index math in clip rendering (hostile stretch values overflowed).

Surround:
- main and bus formats up to 9.1.6 and Ambisonics; pairwise constant-power
surround panner (divergence, centre, LFE, height) per track and send;
ITU fold-down; multichannel bounce with correct WAV channel masks;
multichannel device output; surround panner and multichannel meters in the
Mix window; setup.main_format, mix.surround_pan, mix.send_surround_pan
VST3:
- soundcraft-vst3-host: isolated unsafe crate (vst3 bindings, MIT), scans
standard folders, hosts components/processors/controllers, params,
latency, notes; VST3 menu; engine.vst3_plugins; e2e tests with a fixture
Hardening:
- positions from parameters clamped; offline renders capped and bounded to
track material; loop/transport limits; hostile-parameter property test
