OVERVIEW
Messor is a stereo compressor with
lots of tricks up its sleeve. From
glueing a mix together to squashing
drums and sidechaining kicks, this
versatile dynamics manager does it all.
At its core is a VCA based feed-
forward compressor with a low noise
signal path. The magic is in the side-
chain that shapes the gain reduction.
This starts with a precision envelope
follower, and is then shaped by control
parameters familiar to a compressor:
the attack, release, threshold, ratio
and makeup gain.
The ratio can go past limiting and
into over-compression, which can
completely reshape transients, a great
tool for sound design. A very useful
extra feature is the sidechain filter,
switchable between high-pass and
low-pass to really dial in the
compression response.

The gain reduction envelope is also
available as an output, so you can
patch it into filters, vca's or even
pitch inputs for many creative
explorations using compression as a
starting point.
Being modular, of course there are
CV inputs for Attack, Release and
the side-chain Filter cutoff. The Gain
CV controls the makeup gain, but
also doubles as a Stereo VCA with
the Gain knob turned fully CCW.
There is a bypass switch, and a
Warm mode, that can bring in a bit
of additional saturation and
compression in the form of analog
tube simulation circuitry. Lastly
there's the possibility to insert an
external sidechain, for that classic
kick sidechain compression.
