VOLT

Precision Volt Offset

The VOLT is a precision voltage source and offset generator for eurorack modular synthesizers.

With it’s 14V range (-7V to +7V), VOLT can be used to calibrate oscillators, filter tracking, or anything that needs a 1V/oct calibration.

VOLT has two buttons. Push the top to increase the voltage by one volt. Push the bottom button to decrease the voltage by one volt. Push both buttons at once to reset the voltage back to a known value.

VOLT has 3 voltage inputs and 3 voltage outputs. The input signal is summed with the voltage source, generating offsets of 1V or 1 octave at a time. This means it can be used as a precision octave switch for oscillators that lack the functionality. Create variation in your sequences with a quick touch of a button.

VOLT’s octave buttons can also be switched via external gates, essentially making it an octave sequencer. One input causes it to go up, and the other causes it to go down. Two gates at once will reset the voltage back to your set value. Running basslines and melodies through volt to be sequenced up and down by octaves is a very effective and a fun way to work.
