Controlling The Ultratwin Via Midi - Behringer Ultratwin GX210 User Manual

97-99 Speaker Cabinet: This algorithm emulates three different types of speaker cabinets. Additionally, you
can shift the speaker's main resonance peak. Various degrees of resonance emphasis allow you to
emulate different speaker characteristics. The PARAMETER control adjusts the cutoff frequency of the
low-pass filter. EFFECT A determines the gain of the resonance filter. EFFECT B can be used to adjust
the filter frequency.

3.2 Controlling the ULTRATWIN via MIDI

With its built-in MIDI interface you can integrate your ULTRATWIN into any MIDI setup. The GX210 is capable
of receiving both program change and MIDI controller information. So, you can change programs via MIDI using
a MIDI foot controller or a computer-based sequencer software. Our MIDI foot controller FCB1010 gives you
precisely these and more options, and is a perfect match for all BEHRINGER guitar amps. For example, you
could wire the ULTRATWIN as follows:
Connect the MIDI IN jack of your ULTRATWIN to the MIDI OUT jack of a MIDI foot controller (see fig. 2.2). Now,
enable the MIDI functions on your ULTRATWIN by pressing both UP and DOWN (multi-effects processor) for
about two seconds. Select a MIDI channel (1 through 16, "ON" = Omni mode, "OF" = off and 1 through 16, or
"On" (Omni) plus decimal point = Store Enable mode, see chapter 3.2.1). Confirm your selection with ENTER.
Omni mode means that your ULTRATWIN receives and processes MIDI information on all channels. Of course,
you should select the same channel both on your MIDI foot controller and ULTRATWIN (see MIDI foot controller
user's manual).

Once you activate the MIDI functions, the automatic effect-to-channel assignment feature will
be disabled, i.e. changing channels does not automatically load the previously set effect. As
this assignment feature would cause some confusion when controlling the ULTRATWIN via a
MIDI foot controller, it makes sense only when it is controlled from the enclosed footswitch or
directly from the ULTRATWIN's front panel. To operate the ULTRATWIN without MIDI remote
control, please disable the MIDI functions (display reads OF).
You can select presets via MIDI using program change instructions. Since the range of program change
numbers is 0 through 127, program change instruction 0 corresponds to preset 1, #1 to preset 2, and so forth
(see table 6.2 in the appendix). After changeover the preset is activated immediately, i.e. it will not be affected
by previously adjusted bypass settings.
The three adjustable parameters PARAMETER, EFFECT A and EFFECT B can be controlled in real time from
a MIDI foot controller. First, select a controller number for the foot pedal on your MIDI foot controller (controller
numbers 12 (PARAMETER), 13 (EFFECT A) and 14 (EFFECT B)). Then, use the foot pedal on your MIDI foot
controller to adjust the values for the three parameters.
Channel changes can be effected with controller #10. Sending value 0 via this controller will activate the CLEAN
channel, while value 1 activates the OVERDRIVE channel. Program change instructions can also be used to
change channels. Program change #123 activates the CLEAN channel, program change #124 selects the
OVERDRIVE channel of your ULTRATWIN. In addition to changing channels, you can also disable effects, by
sending the value 0 via controller #11. Value 1 enables the effect. Alternatively, you can bypass the effect
section by sending program change instruction #127.
MIDI controller #7 adjusts the input sensitivity of the effects module, enabling you to set the overall volume of
your ULTRATWIN as desired. Since this controller has no influence on the Master Volume control, you should
adjust the maximum volume before with the Master Volume control, then use MIDI controller #7 to reduce the
volume. This function is also known as "Volume Controller".
The operating range of the wah effect can be determined with MIDI controller #15.
