- Add per-channel amplifier (0-100, 1.0x to 10.0x) applied to intensity
before limiter gates strength
- Fix heat map scaling: use LimitScaleA/B (valA/DesiredA ratio) instead
of valA/200 — was capping colors at green, never reaching orange
- Scale heat map intensity by limiter ratio so colors reflect actual
output after limiter
- Remove dead LastIntensityA/B field (replaced by heat map scaling)
- Amp trackbars: 0=1.0x, 100=10.0x, integer value labels
- Close button quits app instead of hiding to tray
- OnFormClosing no longer intercepts close button — app quits on X
- Minimize still hides to tray (OnResize unchanged)
- Removed unused _closingFromTray flag
- Tray Exit and tray double-click restore unchanged
- DrumDetector.cs: 3-band onset detection (kick/snare/brass) with adaptive
thresholds, per-sub-tick timing within 100ms frames
- Kick: low-band onset, 150ms deep thump
- Snare: broadband (mid+high) onset, 50ms mid punch
- Brass: high-only onset, 10ms buzzy
- Priority: kick > snare > brass when multiple hit same sub-tick
- Intensity = max (100) on hit, 0 on silence — user limiter scales down
- MusicAnalyzer: add BuildMelodyFrame for chB only (pitch+energy)
- LiveCapture: chA now from DrumDetector, chB unchanged (melody)
- Sub-tick mapping: FFT window position → 0-3 within each 100ms tick
- Remove Music button, OnMusic/RunMusicAsync/StopMusic and all music fields
- MusicAnalyzer: remove Analyze, DecodeToMono, MusicPattern record;
keep ExtractFeatures/MapPitchToPeriod/BuildWaveFrame/TickFeature (used by LiveCapture)
- Remove unused NAudio.Wave and System.Diagnostics imports from MainForm
- Fix LiveCapture overlap: sliding window with 50% overlap (was dropping every other frame)
- Buttons resized to 80px (Test/Live/Pattern/Stop All)
- LiveCapture.cs: real-time WASAPI loopback capture with rolling buffer
and continuous FFT analysis, enqueues WaveFrames at ~10Hz
- MusicAnalyzer.cs: refactored ExtractFeatures/MapPitchToPeriod/BuildWaveFrame
as public reusable methods with sampleRate parameter
- MainForm: audio device selector (defaults to system default), Live button
starts/stops capture, Stop All stops live too
- Adaptive normalization (running max with slow decay) for live volume changes
- Swap checkbox moved up to the Connect/device line
- Limiter values shown as separate labels (plain, 32px wide for 3 digits)
- Trackbar keyboard: Up/PageUp/Home = increase, Down/PageDown/End = decrease
- Fix Lim B trackbar clipping (moved down to avoid overlap with Lim A)
- Heat maps fed from tick loop via BeginInvoke (10Hz, one column per tick)
- BLE label updates on ConnectionChanged event (was 4Hz poll)
- Recv gauges update on StrengthChanged event (B1 notifications)
- Button states refreshed via RefreshButtonStates on all state changes
- Status timer reduced from 250ms to 1s — only music label + tray icon
- Eliminates 4Hz choppy polling
- Separate Lim A / Lim B trackbars (0-200, default 30 each)
- Separate Scale A / Scale B checkboxes (clamp vs scale per channel)
- State.SetLimitA/SetLimitB with independent LimitModeA/LimitModeB
- ConsumeTick applies per-channel limit and mode
- Send gauges now show waveform intensity (0-100) not strength ceiling
- State.LastIntensityA/B tracks average intensity per tick
- Zero when no pattern/stream active (was 25 due to IntensityOff 101 sentinel)
- Recv gauges unchanged (device-reported strength 0-200)
- Four gauges: Send A/B (commanded) and Recv A/B (device-reported)
- State.LastSentA/B tracks what would be sent after limiting
- ConsumeTick always runs; only SendB0 gated on IsConnected
- Stream queues drain correctly in dev mode (no box)
- Tray icon hot state works without BLE connected
- Removed strength text label, widened form to 420x360
The manual OnLimitChanged(null, EventArgs.Empty) call in the constructor
was placed before _chkScale was created, causing a NullReferenceException
because the handler reads _chkScale.Checked. Moved the call to after both
_limitBar and _chkScale are created and wired.
- Renamed from CoyoteBridge to Substation (namespace, classes, UI)
- BLE connection via WinRT with graceful disconnect handling
- WebSocket server (127.0.0.1:8765) with single-client, push events
for BLE connect/disconnect transitions
- Operator strength limiter (clamp/scale modes, default 30)
- Tray icon with 3 states: neutral/active/hot (runtime-drawn voltage glyph)
- A/B strength gauges, hide-on-minimise to tray
- Music mode: MP3 decode + FFT analysis (NAudio + FftSharp), rhythm→ch A,
melody→ch B, pre-analyzed with synced audio playback
- Test/Stop All work without BLE connected (dev mode)
- WS device-driving commands error when BLE not connected; ping/status/
connect always work
- TreatWarningsAsErrors, LangVersion=latest
- .gitignore, README with full API docs + attribution
