position increases that value, pulling back to heel position decreases the 

value.

   The expression pedal inputs can also be used as control signal inputs. 

This enables you to use your MF-105M with virtually any control signal 

source: modular analog synthesizers, MIDI-to-CV converters, etc. You 

will find information on interfacing your MF-105M with external control 

signal sources in the Technical Information section on page 23.   

USING MIDI WITH THE MIDI MuRF

     Up to this point, we have described the use of the MIDI MuRF in 

the analog realm. The MIDI MuRF can be controlled via MIDI as well, 

allowing the creation of tempo-synced effects or automated effects when 

used with the MIDI MuRF controller software, a MIDI sequencer or a 

powerful MIDI controller like the MP-201 Multi-Pedal. This makes it 

a very powerful tool in the modern production environment. Note that 

the following sections assume the reader is already familiar with the 

basics of MIDI and the MIDI messages used to control the MIDI MuRF. 

It is beyond the scope of this manual to explain the basics of MIDI 

messages. Basic information about MIDI can be found at the website 

www.MIDI.org. 

SETTING THE MIDI CHANNEL

     The MIDI MuRF Defaults to MIDI Channel 1 for receiving Channel 

Mode messages (MIDI CCs, MIDI Note Ons). The MIDI Channel can be 

set by the user one of two ways: powering up with the LFO and FREQ 

switch in the left position and with the stomp switch pressed sets the 

MIDI channel to 1-12 corresponding to the position of the pattern rotary 

switch. In addition, a MIDI CC #102 with values 1-16 received on any 

MIDI Channel will set the MIDI channel to 1-16.  When the MIDI MuRF 

is powered down, the last MIDI Channel assignment is remembered. 

SELECTING PATTERNS WITH PROGRAM CHANGE MESSAGES

     The MIDI MuRF contains 24 patterns in its memory. From the front 

panel, 1-12 are accessed by the PATTERN switch in the BASS voicing
