4 General Description

The intention of the MC-8 serial port and protocol communication is for an external connected HOST to control and
obtain status from the MC-8. The protocol has been designed to focus on two specific goals. The first is HOST
uploading and downloading of MC-8 configuration, and system/effect setups. The second is HOST control of basic
user adjustable parameters.(i.e. input, volume, balance...)
