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

Removed the master effects section from AudioEditor footer:
- Simplified footer to only show transport controls
- Removed master channel strip area
- Removed border separator between sections
Added note to PLAN.md:
- 🔲 Master channel effects (TODO)
- Will implement master effect chain UI later
- Similar to per-track effects but for final mix
- Documented in Phase 7 multi-track features section
This cleans up the UI for now - we'll add master effects
with a proper device rack UI later, similar to how per-track
effects work (collapsible section with horizontal device cards).
