OWNERS MANUAL
INTRODUCTION Thank you for purchasing the RFX MP128 MIDIBUDDY. The MP128 sends standard MIDI program changes to select patches on a MIDI keyboard, digital signal processor, or other MIDI controllable device. DESCRIPTION
through banks 0 through 120. The ones digit is selected by switches 0 - 9. MIDI data is sent only when a 1 - 9 button is selected except as described below. The display will show a "-" in the right hand digit when no MIDI information is sent, or when a 10's UP or DOWN button is pressed. For example; to send program 47, press the 10s UP or 10s DOWN until the display reads "4-" then press the 7 button. When the 7 button is pressed, program 47 is sent out and the number is displayed by the LED readout.

When program "129" is selected, an "SP" is displayed and a MIDI Stop command is sent.
