Chordizer

BMC Chordizer

◊ The goal of the Chordizer was to use a single voltage input and output a quantized
chord of voltages when used with 1v/octave VCOs. A voltage is inputted through the IN jack and
can be modulated by the AUX jack and it's associated attenuator. The voltage range for the input is
0 to 5V.
Offsets to the input voltage are then applied, these offsets are controlled by three pots and
can be negative or positive offsets. When the offset voltage is outside of the voltage range of the
module, it will be transposed down or up an octave automatically to put it back into the voltage
range.
The input voltage and the offset voltages are then quantized. The QUANT knob selects what
musical scale is used to quantize. Before the voltage is finally output, a slew or portamento is
applied, controlled by the SLEW knob.
The module is compatible with 12V or 15V systems without making any modifications. It
also has capabilities to have voltage controllable chord selection.
