Tape Hacking And Vactrol VCO
Side story Tape Hacking And Vactrol VCO. Video demonstration of homemade tape warbler and voltage- controlled oscillator (VCO) with built-in knobs for pitch, modulation and density. In one device, pitch is controlled by the rate at which the LED blinks, adjustable by two knobs with a single TRS output. The other VCO can play continuously or be controlled via pushbutton. Tape manipulation occurs via white LEDs directly facing photocell resistors and encased in black rubber tubes. One vactrol controls a cassette tape looper built from a hacked Walkman. Another vactrol is connected to the amplifier nodes of the Walkman, giving it a distorted variable-phasing effect. This was run through two Moog pedals that control filtration. Prerecorded synth loops were controlled via touchscreen.
