Gateway OS V1.0.8

Gateway OS V1.0.8

Public binary Apple Silicon realtime multicore performance release for Gateway OS.

Status

• Release type: Public binary Apple Silicon realtime multicore performance update
• Version: 1.0.8
• Source code: Not included in this release repository
• Included artifacts:
  • Windows VST3 x64
  • macOS AU
  • macOS VST3

V1.0.8 Apple Silicon Multicore Update

• Pushes high-oversampling Apple Silicon multicore mode beyond the conservative V1.0.7 lane limits.
• Uses the detected Apple performance-core cluster for 16x and 32x oversampling, limited by the selected oversampling factor.
• Keeps smaller modes conservative where thread overhead can dominate:
  • 4x: up to 2 realtime lanes
  • 8x: up to 4 realtime lanes
  • 16x and 32x: up to the detected performance-core count
• On an M2 Max-class 8-performance-core Mac, 16x/32x should report MC: On 8L.
• Extends the Apple Silicon realtime worker hot path so persistent polyphase workers stay ready across audio callbacks instead of repeatedly paying kernel wake latency.
• Retains the low-latency atomic Apple Silicon dispatcher introduced in V1.0.7.
• Keeps oversampling quality and audio output behavior unchanged.
• Keeps Windows VST3 multicore behavior unchanged.

• GitHub macOS build passed auval -v aufx G100 SMfo.
• VERIFYING CUSTOM UI passed.
• Staged macOS AU and VST3 bundles were ad-hoc signed and verified by codesign --verify --deep --strict.

Gateway OS V1.0.5

Gateway OS V1.0.5

Public binary performance release for Gateway OS.

Status

• Release type: Public binary performance update
• Version: 1.0.5
• Source code: Not included in this release repository
• Included artifacts:
  • Windows VST3 x64
  • macOS AU
  • macOS VST3
• Previous V1.0.4 binaries remain available as a separate download.

V1.0.5 Apple Silicon Multicore Update

• Optimizes Gateway OS multicore oversampling behavior on Apple Silicon Macs.
• Detects macOS performance-core topology at runtime instead of targeting one specific chip model.
• Applies to M-series CPUs from M1 onward, including Pro, Max, and Ultra variants, while retaining fallback behavior for future macOS-compatible Apple Silicon systems.
• Leaves realtime headroom for the DAW/audio graph instead of assigning every available performance core to plugin worker threads.
• Balances polyphase oversampling phases across the chosen thread count, so high oversampling modes such as 16x and 32x do not overload the audio callback thread when thread counts are capped.
• Assigns macOS worker threads high interactive QoS for better realtime scheduling behavior.
• Keeps the oversampling result and audio quality target unchanged; this update changes scheduling/threading behavior, not the oversampling sound.

Validation

• GitHub macOS build passed auval -v aufx G100 SMfo.
• VERIFYING CUSTOM UI passed.
• Staged macOS AU and VST3 bundles were ad-hoc signed and verified by codesign --verify --deep --strict.

• VERIFYING CUSTOM UI passed with Cocoa Views Available: 1.
• CI reported AU VALIDATION SUCCEEDED.
• Staged macOS AU and VST3 bundles were ad-hoc signed and verified by codesign --verify --deep --strict.

Highlights

• Correct WaveNet-family oversampling modes: Off, 2x, 3x, 4x, 8x, 16x, and 32x.
• Supported models run at the requested internal multiple with time/dilation scaling to preserve capture feel while reducing aliasing.
• Multicore polyphase mode is designed to reduce oversampling wall-clock CPU cost while remaining bit-identical to single-core mode.
• Main-window OS/MC status readout.
• Theme-color selector with compact dot palette.
• EQ, noise gate, slim, input calibration, IR loading, and pre/post EQ routing included.
