MIDI Control
Expression pedals should have a three-conductor TRS (Tip, Ring, Sleeve)
plug. This type of plug is also referred to as a “stereo plug”. Most
expression pedals are this type. The resistance value of the pedal is not
important.
MIDI CONTROL
The MWB Pro can optionally be controlled by an external MIDI control-
ler such as the Hot Hand MIDI-Exp controller through the MIDI input. All
of the knob parameters as well as morphing can be controlled via MIDI
Continuous Controller messages. Individual presets can be selected by
MIDI
Program Change messages. The MWB Pro can also be put into by-
pass in this way. The following table describes the use of the MIDI input.
MIDI
implementation:
The MIDI Channel is selectable as a Backpage parameter. Please see the
Backpage Parameter
section for more details.
USE WITH HOT HAND
®
While the primary function of the MWB Pro is as a standalone effects
pedal you also have the option of exploring some additional functions
by plugging in a Hot Hand sensor. When a sensor is connected and
enabled, it will control the amount of DRIVE.The maximum amount of
drive you can get by moving the sensor is determined by the position
of the DRIVE knob.
Hot Hand Basics
The Hot Hand motion sensors are sold separately and come in either
wired or wireless versions. Both will work with the MWB Pro. Addition-
ally, the SENSOR IN jack will be compatible with any future Source Audio
sensors. The SENSOR OUT jack duplicates the signals on the SENSOR IN
and can be used to daisy-chain multiple pedals together using the same
Hot Hand sensor.
The Hot Hand ring contains a two axis accelerometer that responds
to acceleration and is not based on any type of proximity to the guitar.
By moving your hand or by changing the position of your hand you can
modulate the effect. For a good description of Hot Hand Theory, down-
load the
Hot Hand Motion Controlled Wah Filters
manual. It is available
at www.sourceaudio.net.
