[. . . ] The MP80 EX is a simple device to use, extending the flexibility of any MIDI controlled device. To understand it better please read and refer to the rest of this manual. OPERATION The LED display on MP80 EX shows the MIDI program number in a octal (count-by-8) bank preset format. The first digit shows the bank number (0 - 7. . ) and will go through all the digits then start over as the UP or DOWN switches are pressed. The first number is 0, then up to 9, then it jumps to 2 with both decimals on and counts up to 7 with both decimals on (7. . ). The exact MIDI program # can be found by the formula (bank #+1) X (patch #+1)=MIDI program #. The MP80 EX has two modes of operation set by dip switch number 6, switch 6 OFF=128 mode, ON=80 mode. The 80 mode has only 10 banks and may be easier to use if you only need access to 80 presets. The UP and DOWN buttons select the desired bank (0 9 or 0 to 7. . ) but MIDI information is only sent when a patch button (0 through 7) is pressed. SELECTING A PRESET Buttons on the pedal are labeled UP and DOWN and 0 - 7. Pressing a numbered button causes a MIDI program change message to be sent. The selected preset number is displayed in the window right hand digit. Pressing the UP or DOWN buttons moves you into the next higher or lower group of 8 presets. INSTALLATION Apply power 7 to 15 volts AC or DC to the power jack on the rear of the MP80 EX or it may be phantom powered through the MIDI jack. While there is no standard for MIDI phantom power there is a convention of pin 1 as ground and pin 3 as hot, the MP80 EX may be phantom powered by 7 to 25 VDC @ 50 ma. Connect the MIDI OUT on the MP80 EX with a standard MIDI cable to the MIDI IN on the unit to be controlled. [. . . ] SETTING THE MIDI CHANNEL NUMBER The MIDI channel is set with DIP switches 1-4 on the rear of the MP80 EX in binary coding, all off=ch 1 all on=ch 16.
