Release Notes

A complete history of every update to MixBus Platinum — new features, performance improvements, and bug fixes.

v1.2.0

February 2026 — Latest Release

Stability and performance release focused on CPU efficiency, plugin compatibility, and reliability improvements across all supported platforms.

  • Fixed: AU validation failure — Resolved an issue where the AudioUnit plugin could fail validation in Logic Pro on Apple Silicon Macs running macOS 15.2 or later.
  • Fixed: Preset loading delay — Eliminated a 150ms UI freeze when switching presets in standalone mode on Windows systems with high DPI displays.
  • Improved: CPU efficiency — Optimized SIMD processing paths for Apple Silicon, reducing CPU usage by 15% on M1/M2/M3 processors. Intel performance unchanged.
  • Fixed: Stereo Enhancer phase coherence — Corrected a phase cancellation artifact that could occur at extreme width settings (>85%) when the output was summed to mono downstream.
  • Fixed: AGC gate threshold — Resolved an issue where the AGC noise gate could trigger incorrectly on low-level program material at sample rates above 96 kHz.
  • Improved: Metering refresh rate — LUFS and TruePeak meters now update at 60fps on all supported platforms. Reduced GPU draw calls by 30%.

v1.1.0

December 2025

Performance and quality-of-life improvements including metering data export, SmartBand EQ refinements, and cross-platform stability fixes.

  • Improved: SmartBand adaptive HF — Refined the adaptive 7th band response curve for smoother transitions on speech-to-music content. Reduced overshoot on transient-heavy material by 40%.
  • Added: Metering data export — LUFS, gain reduction, and TruePeak metering data can now be exported as CSV for compliance logging. Available in standalone mode via the File menu.
  • Fixed: TruePeak Guard latency reporting — Plugin now correctly reports its latency to the host DAW, resolving timing drift when used alongside other latency-compensated plugins.
  • Fixed: Pre-emphasis bypass state — Resolved an issue where toggling Pre-Emphasis bypass could introduce a brief click on FM delivery mode at 192 kHz sample rates.
  • Improved: Preset browser performance — Preset list now loads 3x faster on projects with large custom preset libraries (>200 presets).
  • Fixed: Windows installer path — Corrected an installation issue where the VST3 plugin was not placed in the correct system directory on non-English Windows locales.
