The MML module is a hardware midi message monitor that decodes midi message and displays on 32 independently programmable LED's. Each row has a labeling area, data indicator LED, and program/test switch. The MML has a module global power and data indicator LED and reset switch. NOTE-If the chassis has only MML’s installed, one MML in the chassis needs an MML Sub board. See the MIDI LED MONITOR page for more information.
