CIRCUIT CONFIGURATION

The figure below is a simplified block diagram of the MF-104M Analog Delay.

MIDI CONTROL OF THE MF-104M

The following section explains the MIDI implementation of the MF-104M. 
For information about what MIDI is and how it works, you can go to the 
following web page for tutorials: www.midi.org/aboutmidi/tutorials.php

MIDI CHANNEL

The default MIDI Channel for the MF-104M is Channel one. To change this, 
press and hold both the 

TAP TEMPO

 and 

BYPASS

 switches. While holding 

both, send a MIDI Channel mode message to the Analog Delay on the 
desired MIDI channel. The 

TIME LED

 will flash yellow indicating that the 

message has been received. The MF-104M will now only receive MIDI mes-
sages on that channel. The current MIDI Input channel is stored in memory 
on power down. 

Note: MIDI Clock and System Exclusive messages are NOT Channel Mode messages, 
and are received by the Analog Delay regardless of the current MIDI Input Channel.

MIDI CONTROL CHANGE (CC) MESSAGES

The settings of the Analog Delay can be controlled by MIDI Control Change 
(CC) messages. In addition to the front panel controls, there are a number 
of advanced features that can be enabled and edited with CC messages.

A MIDI CC message has both a CC number from 0-127 and a value from 
0-127. The CC values that affect panel controls replace the physical setting 
of the front panel controls. When the corresponding front panel control 
is changed after receiving a MIDI CC message, the value will return to 
that panel control. MSB/LSB refers to 14-bit MIDI which uses a pair of CC 
messages to obtain higher resolution control. Use the MSB CC numbers to 
control these parameters at 7-bit resolution. 

Note: Moving a panel control while 

receiving MIDI CC messages for that same control will result in conflicting values.

THE FOLLOWING CC MESSAGES CORRESPOND TO PANEL CONTROLS:

PANEL CONTROLS, BUT EXTEND THE ANALOG DELAY’S CAPABILITIES.
