The MASTER module is the base of an AE modular system if MIDI control has to be possible; it contains

• the voltage regulation (5V) for the power supply of the modules
• a MIDI input (minijack; Breakout cable to DIN-5 socket is available separately); the MIDI channel can be selected between 1, 14, 15,16 or OMNI
• In/out-sockets (3.5mm minijack) for audio out and/or interfacing with a Eurorack system
• all bus signals (CV, GATE, CTRL, MIDI clock/start/stop) as patch sockets
