MiniMod Precision Voltages

A precision voltage source and adder for 1V/octave pitch, with two channels that add or subtract whole octaves and notes.

Key features

• An eleven way OCTAVE and a twelve way NOTE switch per channel, each with its own plus, off, minus switch
• With nothing patched a channel is a voltage source; with an input it adds its voltage to it, to +/-2 mV over +/-10 V
• A gate input turns channel A's transposition on and off while the input still passes through
• A combination switch gives A+B, A or A-B
• A calibration output accurate to +/-0.5 mV tunes VCOs without test equipment
