What Bus Processor 670 does
Variable-mu compression uses tubes to alter gain, so the compression ratio changes dynamically with the input signal, and the developer describes the result as harmonically rich and musical.
The plugin adds a saturation control, sidechain options that give control over filters and tone, a shift between mono and stereo linking, and spatialization features that include an air band, a mono maker and stereo widening. The Bus Processor 670 release circulates as a crack for Windows and macOS, and the macOS build is packed as a .dmg crack. The Windows build is typed as x64 crack and x86 crack in searches, and the repack ships as .rar and .iso files.
Key features
- Sidechain options. Sidechain settings give control over filters and tone so the detector can respond to a shaped version of the signal.
- Mono and stereo linking. A shift switches the detector between mono and stereo linking of the two channels.
- Spatialization features. An air band, a mono maker and stereo widening shape the stereo image after compression.
- Flow and Console 1 compatibility. The developer lists compatibility with Softube’s Console 1 mixing hardware and its Flow Studio hardware.
- Included Flow subscriptions. The developer states that Flow Mixing, Mastering and Complete Suite subscriptions are included.
