v1.3.0 (2026-04-12)

- macOS binaries are now signed and notarized — no terminal workarounds needed, includes installer
- Instance overlay now automatically syncs division between instances
- Instance overlay now uses the track color by default
- Fixed sidechain overlay waveform artifacts (since v1.2.6)
- Added update checker
- Smooth waveform movement in Scroll mode
- Band-pass filter now disables itself automatically when activated via the frequency slider
- Sidechain overlay no longer draws ahead of the cursor when instances have different PDC latency
- Faster waveform rendering on large divisions (2 Bar+)
- Improved anti-aliased waveform rendering performance
- Consistent zoom behavior in Scroll mode (Catmull-Rom interpolation, sample dots)
- Sample dots at high zoom now have a fixed size instead of scaling with the zoom level
- Non-AA waveform peaks no longer appear hair-thin at high zoom
- Hold waveform now displays without clipping, showing the full amplitude
- Fixed an issue where Sync mode could draw pre-roll audio at the end of the buffer when starting from a bar boundary with PDC > 0
- Fixed a 1px glitch at the left edge in Scroll mode
- Reset in Sync mode now keeps the cursor at the correct PPQ position instead of jumping to the start
- Track renaming in the host now updates instance names even when the plugin window is closed
- BP audio listening mode (Ctrl+Click) now saves/restores with project state
- BP filter now activates on project load when audio listening mode was enabled
- Default Source menu now immediately switches the active source, not just saves the setting
- Fixed CPU spike on buffer clear
- Fixed waveform micro-jitter in BP mode
