Pitch Modified GPX Cassette Walkman
Selectable Photocell/ Knob Control/ CV Input
w/ Record Function, Built-in Mic, AM/FM radio, and Speaker

Control speed/pitch of the tape via potentiometer as well as selectable light reactive and voltage control. The photocell and cv input are attenuated by the pitch knob. The control voltage feature can be thought of more as voltage reactive and works best within the 0-5V range. Putting the pitch knob in a fast position will increase the amount of influence from voltage or light. Positive voltage pulses and bright light will result in slowing the speed. Synth modules that operate in the 0-10 volt range may cause the unit to come to full stops and starts. This can be used to great effect, but may also cause damage to the circuitry/motor, so please proceed at your own risk! 

Please note: selection switch between photocell or cv input is wired to the reverse of what one might assume. Toggle the switch away from the fuction you would like to utilize. 

Includes two AA batteries. Will run on a 3V negative center adaptor with 4mm barrel - not included.
