Gateway OS V1.0.0 (superseded by V1.0.2)

Gateway OS V1.0.0

Public binary release notes for Gateway OS V1.0.0.

Superseded for macOS users by Gateway OS V1.0.2.

Status

• Release type: Public binary release
• Version: 1.0.0
• Source code: Not included in this release repository
• Included artifacts:
  • Windows VST3 x64
  • macOS AU
  • macOS VST3

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.
