V-Scale

A precision active buffer and multiple: one input to five outputs, with very high input impedance, very low output impedance and less than 1 mV offset, so pitch does not shift when it is patched in or out. Four of the five outputs can be scaled up or down by 5 % from the front panel, to make VCOs and VCFs that do not quite track 1V/octave track correctly without recalibrating them.
