Dirt Clod presets can be recalled using any or all of 128 MIDI Program Changes. Each
MIDI Program Change received by the Dirt Clod can be mapped to one of its 10 presets
or to bypass. See “Mapping Presets” section below for details.
Real-time control of each of the Dirt Clod’s parameters can be achieved using MIDI
Continuous Controller messages. MIDI Expression Pedal data can be assigned to any
of the 4 Dirt Clod knobs as well as the FORM switch (clip style). See “MIDI Continuous
Controllers” section below.
Setting the MIDI Channel
The Dirt Clod defaults to receiving MIDI data on MIDI Channel 1. To change the MIDI
channel for receiving MIDI data, first disconnect power from the pedal. Then, press and
hold the ‘A’ footswitch while applying power to the pedal. The current MIDI Channel will
be displayed. Use the ‘A’ and ‘B’ footswitches to change the channel. Available
channels are 1-16 (channels 10-16 are indicated as 0-6 with the center yellow LED
lighted). To save and exit, simply disconnect power to the pedal. Your MIDI Channel will
be saved.
Mapping Presets
Any MIDI Program Change can be used to load any preset, or to bypass the pedal.
First, send any MIDI Program Change to the Dirt Clod on its set MIDI Channel. The Dirt
Clod should respond by loading a preset or bypassing. If the Dirt Clod is not on the
preset you would like, simply use the controls on the Dirt Clod to select the desired
preset (or bypass it) just as you normally would. However, when making the selection,
continue to hold the footswitch until the LEDs flash, indicating the MIDI change has
been mapped. The Dirt Clod will now make this selected change each time that this
MIDI Program Change is received.
MIDI Continuous Controllers
Any of the Dirt Clod’s knob settings can be controlled in real time using MIDI
Continuous Controllers. The following chart shows the CC#s for the various controls:
Function
CC#
Value
DIRT
34
0-127
CORE
35
0-127
CRYSTAL
36
0-127
MASS
37
0-127
FORM
38
0-63:OFF, 64-127:ON
So as not to cause a jump in parameter value when receiving MIDI CC data, the Dirt
Clod will not begin to respond to MIDI CC data until the received CC value is the same
as the current value of the corresponding control.
