The MA1-PCB (Printed Circuit board) is a powerful Midi analyzer, analyser, tester, decoder display unit that will receive all Midi messages, including controller and system exclusive (Sys Ex), decodes and displays in a user friendly format. Any message type can be displayed or filtered. The MA1-PCB has a HOLD and SCROLL feature and allows scrolling through the last messages received. This PCB is the same PCB  that is used for the MA1 Module (with limited functionality). Also, by ganging multiple MA1's together, each one could be programmed to filter out selected messages, and at a quick glance the latest information is displayed. See the MIDI ANALYZER PAGE for a full description and more information.
