Implemented comprehensive automation recording system for volume, pan, and effect parameters:
- Added automation recording modes:
- Write: Records continuously during playback when values change
- Touch: Records only while control is being touched/moved
- Latch: Records from first touch until playback stops
- Implemented value change detection (0.001 threshold) to prevent infinite loops
- Fixed React setState-in-render errors by:
- Using queueMicrotask() to defer state updates
- Moving lane creation logic to useEffect
- Properly memoizing touch handlers with useMemo
- Added proper value ranges for effect parameters:
- Frequency: 20-20000 Hz
- Q: 0.1-20
- Gain: -40-40 dB
- Enhanced automation lane auto-creation with parameter-specific ranges
- Added touch callbacks to all parameter controls (volume, pan, effects)
- Implemented throttling (100ms) to avoid excessive automation points
Technical improvements:
- Used tracksRef and onRecordAutomationRef to ensure latest values in animation loops
- Added proper cleanup on playback stop
- Optimized recording to only trigger when values actually change

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

- 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.

Created a beautiful effect browser dialog inspired by Ableton Live:
**EffectBrowser Component:**
- Modal dialog with search functionality
- Effects organized by category:
- Dynamics (Compressor, Limiter, Gate)
- Filters (Lowpass, Highpass, Bandpass, etc.)
- Time-Based (Delay, Reverb, Chorus, Flanger, Phaser)
- Distortion (Distortion, Bitcrusher)
- Pitch & Time (Pitch Shifter, Time Stretch)
- Utility (Normalize, Fade In/Out, Reverse)
- Grid layout with hover effects
- Real-time search filtering
- Click effect to add to track
**Integration:**
- "+" button in track strip opens EffectBrowser dialog
- Selecting an effect adds it to the track's effect chain
- Effects appear immediately in the Devices section
- Full enable/disable and remove functionality
**UX Flow:**
1. Click "+" in track Devices section
2. Browse or search for effect
3. Click effect to add it
4. Effect appears in Devices list
5. Toggle on/off with ●/○
6. Remove with × button
Effects are now fully manageable in the UI! Next: Apply them to audio.

Fixed "Cannot read properties of undefined (reading 'toFixed')" errors
in TimeBasedParameterDialog and DynamicsParameterDialog by adding
nullish coalescing operators with default values to all parameter
accesses. This prevents errors when loading presets that have partial
parameter sets.
