Cosmotronic Messor

Analog stereo compression, transient shaping, and sidechain control

8 HP Eurorack module

Messor is an analog stereo feed-forward VCA compressor for mix-bus glue, transient shaping, sidechain pumping, and creative over-compression. Its internal detector combines the stereo inputs, filters the sidechain, and shapes gain reduction with voltage-controllable attack, release, and cutoff. Makeup gain, warm saturation, stereo-VCA operation, and a negative envelope output extend it beyond conventional compression.

Features

  • Analog stereo feed-forward VCA compressor
  • Linked stereo gain reduction from a mono-summed detector
  • Ratio range from off through limiting and negative over-compression
  • Approximately 1-500 ms attack range
  • Approximately 5 ms-3.5 s release range
  • Voltage control of attack, release, and sidechain-filter cutoff
  • Switchable 6 dB/octave low-pass or high-pass sidechain filter
  • External sidechain input with internal stereo-sum normalization
  • Post-compression makeup gain up to approximately +17 dB
  • Gain CV supports stereo-VCA operation
  • Warm tube-style soft-clipping circuit
  • Independent negative gain-reduction envelope output
