This is a simple sampling of a very famous optical compressor that has gorgeous valves in the signal path. It gives a very smooth natural sounding compression. I recommend using it in conjunction with the stunning IK Multimedia T-racks White 2A leveling amplifier ( tm )to get somewhat closer to the real hardware. 15 presets in total were made. 5 presets per sample rate. 10 distortion kernels Please note that these require a fully licensed Nebula Pro license to enjoy. Full commercial package size is 361 MB. Provided at 192 khz, 96 khz and 44 khz.
