Haptic Studio v1.4 Changelog: Multi-Track Curves, 120Hz Preview, and Batch AHAP Export
Complete technical release notes for Haptic Studio desktop v1.4.0 with performance optimizations and bug fixes.
Alexandre Mercier
Principal Systems Engineer
Haptic Studio v1.4.0 is now available for download on macOS and Windows. This release introduces ProMotion 120Hz canvas rendering, batch export for Apple Xcode asset catalogs, and major performance optimizations in our waveform caching engine.
New Features
Key Takeaways
- 120Hz ProMotion Canvas: Ultra-smooth timeline scrolling and playhead movement on Apple Silicon displays.
- Batch AHAP Export: Export multiple cue markers or scene splits into named .ahap asset bundles simultaneously.
- Custom Hotkey Profiles: Pro Tools, Logic Pro, and DaVinci Resolve keyboard shortcut presets.
- Waveform Peak Metering: High-resolution dBFS and tactile intensity meters alongside audio channels.
Performance Improvements
Reduced idle CPU utilization from 4.8% to 0.4% via efficient event-driven window repainting. Audio waveform cache serialization now uses SIMD-accelerated binary decoding.
Bug Fixes
Fixed an issue where scrubbing during video playback could occasionally drop the first transient event. Resolved Wi-Fi preview connection drops on certain mesh router configurations.
