17381221d8 feat: refine UI with effects panel improvements and visual polish 
Major improvements:
- Fixed multi-file import (FileList to Array conversion)
- Auto-select first track when adding to empty project
- Global effects panel folding state (independent of track selection)
- Effects panel collapsed/disabled when no track selected
- Effect device expansion state persisted per-device
- Effect browser with searchable descriptions

Visual refinements:
- Removed center dot from pan knob for cleaner look
- Simplified fader: removed volume fill overlay, dynamic level meter visible through semi-transparent handle
- Level meter capped at fader position (realistic mixer behavior)
- Solid background instead of gradient for fader track
- Subtle volume overlay up to fader handle
- Fixed track control width flickering (consistent 4px border)
- Effect devices: removed shadows/rounded corners for flatter DAW-style look, added consistent border-radius
- Added border between track control and waveform area

9b1eedc379 feat: Ableton Live-style effects and complete automation system 
Enhanced visual design:
- Improved device rack container with darker background and inner shadow
- Device cards now have rounded corners, shadows, and colored indicators
- Better visual separation between enabled/disabled effects
- Active devices highlighted with accent border

Complete automation infrastructure (Phase 9):
- Created comprehensive type system for automation lanes and points
- Implemented AutomationPoint component with drag-and-drop editing
- Implemented AutomationHeader with mode controls (Read/Write/Touch/Latch)
- Implemented AutomationLane with canvas-based curve rendering
- Integrated automation lanes into Track component below effects
- Created automation playback engine with real-time interpolation
- Added automation data persistence to localStorage

Automation features:
- Add/remove automation points by clicking/double-clicking
- Drag points to change time and value
- Multiple automation modes (Read, Write, Touch, Latch)
- Linear and step curve types (bezier planned)
- Adjustable lane height (60-180px)
- Show/hide automation per lane
- Real-time value display at playhead
- Color-coded lanes by parameter type
- Keyboard delete support (Delete/Backspace)

Track type updates:
- Added automation field to Track interface
- Updated track creation to initialize empty automation
- Updated localStorage save/load to include automation data

Files created:
- components/automation/AutomationPoint.tsx
- components/automation/AutomationHeader.tsx
- components/automation/AutomationLane.tsx
- lib/audio/automation/utils.ts (helper functions)
- lib/audio/automation/playback.ts (playback engine)
- types/automation.ts (complete type system)

Files modified:
- components/effects/EffectDevice.tsx (Ableton-style visual improvements)
- components/tracks/Track.tsx (automation lanes integration)
- types/track.ts (automation field added)
- lib/audio/track-utils.ts (automation initialization)
- lib/hooks/useMultiTrack.ts (automation persistence)

beb7085c89 feat: complete Phase 7.4 - real-time track effects system 
Implemented comprehensive real-time effect processing for multi-track audio:

Core Features:
- Per-track effect chains with drag-and-drop reordering
- Effect bypass/enable toggle per effect
- Real-time parameter updates (filters, dynamics, time-based, distortion, bitcrusher, pitch, timestretch)
- Add/remove effects during playback without interruption
- Effect chain persistence via localStorage
- Automatic playback stop when tracks are deleted

Technical Implementation:
- Effect processor with dry/wet routing for bypass functionality
- Real-time effect parameter updates using AudioParam setValueAtTime
- Structure change detection for add/remove/reorder operations
- Stale closure fix using refs for latest track state
- ScriptProcessorNode for bitcrusher, pitch shifter, and time stretch
- Dual-tap delay line for pitch shifting
- Overlap-add synthesis for time stretching

UI Components:
- EffectBrowser dialog with categorized effects
- EffectDevice component with parameter controls
- EffectParameters for all 19 real-time effect types
- Device rack with horizontal scrolling (Ableton-style)

Removed offline-only effects (normalize, fadeIn, fadeOut, reverse) as they don't fit the real-time processing model.

Completed all items in Phase 7.4:
- [x] Per-track effect chain
- [x] Effect rack UI
- [x] Effect bypass per track
- [x] Real-time effect processing during playback
- [x] Add/remove effects during playback
- [x] Real-time parameter updates
- [x] Effect chain persistence

6bfc8d3cfe feat: implement horizontal device rack with collapsible effect cards 
- Created EffectDevice component with expand/collapse state
- Each device shows name, type, enabled/disabled toggle, and remove button
- When expanded, devices show parameter details
- Replaced vertical effect list with horizontal scrolling rack
- Effects display in 192px wide cards with visual feedback
- Power button toggles effect enabled/disabled state
- Parameters display shown when expanded (controls coming soon)

This matches the Ableton Live/Bitwig workflow where effects are
arranged horizontally with collapsible UI for each device.
