The MA1 also displays Midi statistics including: framing, timing and overrun errors, active sense, clock, Midi Time Code and a filter on/off indicator. Features front access LCD brightness and contrast adjustments. 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. The filtering function will filter out any Midi message type that doesn't need to be stored or analyzed.

    Two Display Types: DECODE and HEXADECIMEAL

     Decode Display: Shows the type of message, channel number, and decimal equivalent of the data. The 'Note' information can be viewed as the decoded note or as a note number. Middle C can be changed from C3, C4, or C5. In the HOLD mode the last few bytes can be displayed and scrolled through, including a message counter. Any message type can be filtered out. An indicator shows if 'Midi Time Code' (F1), 'Time Clock' (F8), and 'Active Sensing (FE) messages present whether they're filtered or not. System Exclusive messages are displayed with all the associated bytes that can be scrolled through independently too and displays a total byte count and an individual byte counter.

     HEX Display: The data is displayed in a Hexadecimal format for technical viewing, and displays the data AS IS without any decoding. In the HOLD mode the last 112 bytes can be displayed and scrolled through, including a byte counter. 'Midi Time Code' (F1), 'Time Clock' (F8), and 'Active Sensing (FE) messages can be filtered out. An indicator shows if those messages are present whether they're filtered or not.
