Sonimus has released TuCo, a compressor plugin based on vari-mu tube technology with a feedback topology. TuCo can be clean, warm and crisp at same time, getting subtle and natural compression at low amounts and punchy at higher amounts. TuCo is an original Sonimus development, designed fresh using analog modeling techniques, not an emulation of any vintage analog hardware.
Sonimus TuCo is available now for $74. It requires macOS 10.8 or later and an AU, VST, or AAX plugin host.
