The CPU label in the UI was showing psutil.cpu_percent(interval=None)
which returns total system CPU — barely moves and doesn't change when
the NAM model is bypassed.
Fix:
- Added _calc_nam_cpu() that computes NAM engine CPU from the engine's
own per-block inference timing (avg_inference_ms) vs the JACK callback
interval. When the NAM block is bypassed in the chain, returns 0.
- Added 'nam_cpu' field to /api/state response
- Status bar shows NAM CPU % next to VU meters (drops to 0 on bypass)
- Settings CPU row shows NAM CPU with system CPU in dim text beside it
- Changed psutil.cpu_percent(interval=None) → interval=0.2 for a real
system CPU reading
Shows input (green) and output (amber) level bars in the status bar,
updated every 2s from /api/state. Scales factor 300x to make small
signals visible, capped at 100%.
The profile change handler was calling nam_host.set_block_size() AFTER
jack_client.start(), creating a race where the JACK callback fired with
the new buffer size while the old NAM subprocess was still running at
the old block_size. Pipe byte counts desynced => NAM returned passthrough.
+ also: auto_connect disable during restart, connect_fx_ports reorder,
Tone3000 gear/sort/pagination params, NAM engine switch API endpoints
The setAudioParams call restarts JACK which takes up to 10 seconds.
The default API timeout was 6s, causing the request to abort and
leaving JACK in a broken state.
- Changed setAudioParams to use API._fetch directly with timeout:15000
- Also calls loadAudioParams() after success to refresh dropdown values
- NAM/IR tab toggle in Downloads overlay
- Architecture filter (All/Nano/Feather/Standard) - filters via
Supabase architecture_version column
- Model detail overlay: tap a search result to see full description,
gear info, author, pack, architecture, thumbnail before downloading
- IR search + install with .meta.json metadata saving
- Backend: search_models/get_trending_models accept arch param
- Backend: tone_gear field added to model search response
- UI now sends full Tone3000 metadata on install (id, author,
architecture, pack_name, description, thumbnail, etc.)
- Search results show size, architecture, and pack name
- Install endpoint saves a .meta.json file next to each .nam with:
author, architecture, description, pack, thumbnail, download date
- Enables offline browsing of model provenance
- Audio devices endpoint now includes Bluetooth Audio (bluealsa) and
other software PCM devices from aplay -L
- Added GET/POST /api/backing-source endpoints with JACK port routing
- Backing Track Source dropdown in Audio section (None, Bluetooth
Audio, or any JACK capture port found)
- Selecting a source routes it into fx_in:input_2 via jack_connect
- Also supports bt_audio:capture_1/2 from existing JACK bridge
- Added Output Device dropdown alongside Input Device
- loadAudioDevices() now populates both dropdowns from the API and
selects current values
- Separated setAudioInputDevice / setAudioOutputDevice functions
(each calls API with only its respective field)
- Added input_device / output_device to GET /api/audio/profile response
- Removed the old combined setAudioDevice function
- Moved .settings-nav out of .overlay-body so it stays pinned below
the header when scrolling
- Buttons bumped to 12px font, 8px 16px padding, 38px min-height
- Added gap, padding, background and border-bottom to nav strip
Adds a scrollable row of section tabs at the top of the settings
overlay: Network · Audio · Interface · Bluetooth · System.
Each tab scrolls smoothly to its section and highlights as active.
- Changed both tab bar ⚙ and status bar ⚙ buttons to open the
inline Settings overlay (openOverlay('Settings')) with data loads
instead of navigating to /settings (old Bootstrap page)
- The overlay was already fully built — HTML, CSS, JS loaders were all
present, just never wired up
Both the tab bar ⚙ Settings button and the status bar ⚙ button
in the v2 UI now redirect to /settings instead of opening an
inline overlay. The full settings page has the left sidebar nav
with category views.
