An accurate voltage source and precision adder. Voltio fits somewhere between a music tool and a piece of electronics lab gear. It generates voltages equivalent to all the notes on the 12-tone equal temperament scale throughout a ten-octave range, with an intuitive two-knob interface.
The Precision Adder In, lets you sum Voltio’s Out with external voltages. Additionally, the front panel banana connectors let you plug standard multimeter probes for hands-free operation on electronics lab.
Use it to transpose Oscillators and sequences in a musical way or as a reference to calibrate your analog gear.
