Pico MScale

Erica Synths Pico MSCALE (Moog Scale, to be specific) is precision scaler to adapt Moog Mother 32 to eurorack standard 1V/oct control voltages.

People who own Moog Mother 32 know that it requires -5V – +5V on 1V/oct input to operate in full range, while the eurorack standard is 0V – +10V. So, to control Moog Mother 32 from a eurorack sequencer you need to bias a sequencer output for 5 volts down. And vice versa – Moog Mother 32 sequencer outputs -5V – +5V on 1V/oct output, and, if you wish to control some eurorack VCO from Moog Mother 32, you need to bias it 5 volts up. This is exactly what MSCALE does – it has two sections – upper one adds 5V to the input voltage, other subtracts 5V form the input voltage. Of course, the module is not limited for use with Moog Mother 32 only. You can use it as a regular eurorack precision voltage scaler.
