Muzzle is a voltage controlled 12db multiband filter.
A nice filter for all your filter duties features.
It's VCFs based on LM13700 chips, sounding like the classic SH and System filter.
Simultaneous outputs of low pass, high pass, and band pass filter types are provided allowing for many variations of the input signal.  

MASHUP is a simple 3 stereo channel audio mixer.
All stereo inputs with simultaneous volume adjustment on both channels and mute.
Total mix Left and Right outputs available on separate jacks.
AC coupled inputs. 

SEPAGE is a simple dual 4-stage envelope generator with independently
adjustable ATTACK, DECAY, SUSTAIN, and RELEASE stages.
LEDs are output indicators and illuminate according to the output level.
The ADSR outputs can be used to control the amplitude of an oscillator,
the cutoff frequency of a filter or any other function on a module that
accepts control voltages. 

Slit is a frequency divider for clock. The clock divider analyses an incoming clock and divides it by 2, 4, 8, 16, 32 and 64. The low/high levels of the output signals are 0V and about +10V. Each divisor has a separate gate output and their activities are displayed with individual LEDs.
A trigger impulse at the reset input zeroes the entire module.
