These were all paper circuits
The module is thus for experimentation
It's wealth of connection jacks allows it to be connected to the MS-20 and a variety of other synthesizers
originally designed for controlling the light boxes of Dan Conrad
” which correspond directly to the bounce/bounds dialectic as well as that of the triangle/square
Shifting Inverting Signal Mingler (SISM) OOS These were all paper circuitsThe SISM is a 4 channel voltage manipulator that can scale, invert, attenuate, shift (dc offset), mix, split, and slice your CV and audio signals. A plethora of red and blue LEDs (14) show exactly what each channel and output jack is doing: red = negative voltage, blue = positive. Each channel is independent and has an input jack, output jack, a knob for attenuating inverting (Scale), and a knob for applying positive or negative DC offset (Shift).
