flo kaufmann shows his "satrap activ" portable analog synthesizer made out of a vacuum cleaner

The "satrap activ" is a old vacuum cleaner from the 70ies, converted into an analog synthesizer.
It contains 2 cmos based VCO's , a Moog ladder filter, a 555 based ADSR, a cmos based 8 step sequencer, a PIC based vc to midi interface and a PIC based auto trigger unit.
There are 4 tunable knobs on top, mostly to play bass-lines, and 2 conductable wires, which act as voltage dividers to generate variable tones. the wires do not vibrate. so it is not a cord instrument. satrap activ can also control other synthesizers either by midi or cv/gate interface.
