INTRODUCTION

Thank you for purchasing the ROLLS MP80 Midi Pedal, it is designed to provide lasting

value and usefulness. MIDI provides standardization from which many manufacturers can

create products to interface with each other. It has a lot in common with the RS232 for

computer data except MIDI is better thought out and is more of a true standard. MIDI is

supported for all popular computers, and hardware and software support are increasing

daily. Also since it has such wide support, MIDI is now being used for some non musical

applications. The ROLLS MP80 is a controller for sending MIDI program change informa-

tion on any of the 16 MIDI channels. This is done in 10 banks (or groups) of 8 patches (or

presets). The 2 digit display shows the bank and patch numbers and does not necessarily

equal the MIDI program number being accessed. The left digit is the bank # and the right is

the patch # (or preset #). The exact MIDI program # can be found by the formula (bank #+1)

X (patch #+1)=MIDI program #. The MIDI channel # is set by dip switches on the front of

the unit, switches 1 - 4 off is MIDI channel 1, switches 5 & 6 are not used at this time. The

UP and DOWN buttons select the desired bank (0 - 9) but MIDI information is only sent

when a patch button (0 through 7) is pressed.

INSTALLATION

Apply power 7 to 15 volts AC or DC to the power jack on the front of the MP80 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 may be phantom

with a standard MIDI cable to the MIDI IN on the unit to be controlled. It may be used on

the floor and foot switched or placed on top of a keyboard for easy hand access. The MP80

is designed so it can be stored in an extra space in a 19 inch audio rack.

USING THE ROLLS MP80

Since the MP80 is organized in groups of banks some programming of the unit being con-

trolled in patch groups of 8 can make commonly used sounds very easy to get at. When the

MP80 is first powered up the bank digit will sometimes be blank, simply press the up button

until it lights. The MP80 follows the MIDI standard protocol and will work with any MIDI

controllable device. Make sure the MIDI channel numbers match so both units are “talking”

on the same channel, most MIDI controllable devices have an omni or all channel mode this

can sometimes be used to avoid channel confusion.

SETTING THE MIDI CHANNEL NUMBER

The MIDI channel is set with DIP switches 1-4 on the front of the MP80 in binary coding, all

off=ch 1 all on=ch 16. Down=on
