The filter's layout is pretty clear: it has potentiometers for setting cutoff frequency and resonance. Both parameters are voltage controlled and the modulation depth of each CV can be adjusted with atttenuators.
The MST low pass filter can oscillate and thus be used as a sine wave oscillator becuase it has a 1V/octave input for controlling it's frequency.
Two slopes are available simultaneously: -12dB and -24dB per octave.
The MST series is a cooperation between Synthrotek and George Mattson, the designer of the the Mattson Mini Modular.
