Control Voltage Modulation
[No Longer In Production]
The VC Bend is designed as a way to create less than certain variations from pre-determined control voltages, like transposing / inverting a bassline into a melody or creating a 3rd envelope from 2 sources. Used at audio rate, it acts like a voltage controlled full wave rectifier. The VC Bend favours 'esoteric' applications over precision. More often than not the output voltage will not resemble the input. Functionally, the VC Bend sits somewhere between a sample and hold and a quantizer module. However, the type of modulation produced is completely unique to the VC Bend.
The VC Bend takes a bipolar (positive or negative) control voltage input and modulates it by the amount of the CV Input in relation to the Internal Voltage Reference. The output is a voltage which is always above 0V, the direction (moving with or away from the input) of which can be altered with an external voltage.
Voltage Controlled Control Voltage Bender
Full Wave Rectifier - The output is always a positive voltage. Converts a bi-polar input voltage (generally +/-5V) into a uni-polar output voltage (0-10V).
CV Amplifier. Both IN and CV inputs have attenuverted knobs to control polarity and gain (2X positive and negative gain).
MAIN - Attenuverted Gain Knob for the IN input. Knob zeros out at 12 o'clock.
MOD - Attenuverted Gain Knob for the CV input. Knob zeros out at 12 o'clock.
INT - Internal Voltage Reference Knob (0v - 10v).
IN - The signal to be modulated. Input can be positive or negative CV or audio rate signal.CV - The modulation source. Input can be positive or negative CV or audio rate signal.
OUT - Modulated signal output. Output can be positive CV or audio rate signal.
Power Usage: 20mA
The VC Bend circuit was designed by Thomas O’Connor.
