Controlling the Opt-2A plug-in parameters
Opt-2A is a processor that emulates a standard vintage model of vacuum tube optical compressor. The level
is controlled using optical components such as a CdS-Cell and EL panel to produce smooth compression. The
beautiful high-frequency overtones in the warm distortion created by the vacuum tube circuit generate an
elegant and sophisticated sound.
