Breakout expansion for the Grendel Drone Commander 2

With the optional Expander module, the system gains eighteen patch points for CV, gate + trigger, and audio. Its clock input allows synchronization to analog clock sources, and AUX IN lets you process external audio sources. As a bonus, the voltage ranges of some of the inputs and outputs can be switched between +/-2.5 volts and 0..+5 volts, facilitating connection to other synth modules, MIDI-CV converters, and various tabletop analog gear.

Current consumption is 120mA @ +12(+15) volts for the combined Main Module + Expander, and 2.5mA @ -12(-15) volts, 0 mA @ +5 volts.
