What OmniTec-436C does
The plugin draws its character from the Altec 436C, a vari-mu compressor that was quickly adopted by producers and later used on many significant recordings. The developer says the 436C then established itself in pop music studios across the US and Europe, and OmniTec-436C keeps its core behavior while modernizing the controls.
Tube-based modeling gives the compressor a smooth, mellow tone that the developer describes as highly musical. The plugin is offered for vocals, strings, brass and synthesizers, and the developer adds a signature Black Rooster Audio touch to the vintage sound.
