FEEDBACK DESTROYER PRO FBQ2496
7. MIDI CONTROL
MIDI stands for “Musical Instrument Digital Interface.” It is a
“language” used to transmit control information between different
electronic devices: instruments, PCs, drum computers, effects units,
etc. That way, a device ’s parameters can be automatically modified
at a previously determined point in time.
To make such communication possible, the following conditions
have to be met:
s
All devices must be correctly connected to one another.
s One device, called “master,” sends MIDI information via one
or several MIDI channels. The device receiving control
information, called “slave,” has to be set to the correct MIDI
channel in order to receive the information.
s The control information being sent has to be “understood” by
the MIDI devices receiving it.
7.1 MIDI connections
The MIDI connectors found on the rear panel are on internationally
standardized 5-pin DIN jacks. You need dedicated MIDI cables to
connect the FBQ2496 to other MIDI equipment. Normally, complete
cables will be purchased for this use. MIDI cables should have a
maximum length not exceeding 15 meters.
MIDI IN: Receives MIDI control data. The receive channel is
determined in the SETUP menu.
MIDI THRU: Provides an unchanged copy of the signal received at
the MIDI IN, for example, to daisy-chain several FBQ2496.
MIDI OUT: Transmits MIDI data to a connected computer or other
FBQ2496. Transmitted are program data as well as status
information for signal processing.
+
No loop lines are allowed with MIDI connections, i.e. the
master device can send only control information, and the
slave device(s) can only receive control information –and
not the other way around. Depending on your
application, some devices can function both as masters
and slaves.
7.2 Activating and deactivating MIDI
With some applications, having the option to disable the MIDI
function of a device can be useful. This means that the device
does not react to the incoming MIDI control data; instead, it merely
passes the incoming MIDI signal through.
The FBQ2496 gives you the option to decide whether it should
react to incoming MIDI control data.
+
Even when the MIDI function is deactivated on the
FBQ2496, the MIDI signal still passes through the unit and
can be tapped into at the MIDI THRU connector.
1. Press BANDWIDTH and BYPASS simultaneously. The MIDI
menu is activated if the LEDs on both buttons as well as the
MIDI LED under the display are blinking.
2. Press the BANDWIDTH button; then use the wheel to activate
or deactivate MIDI.

3. Press any button to exit this menu.
7.3 Adjusting a MIDI channel
Using a MIDI channel, a master can transmit 16 different data
segments, each one using its own channel. To make sure a slave
only receives the information intended for it, the corresponding
MIDI channels have to be assigned to it first.
1.
Press BANDWIDTH and BYPASS simultaneously. The MIDI
menu is activated if the LEDs on both buttons as well as the
MIDI LED under the display are blinking.
2. Press BANDWIDTH again. Now, a MIDI channel can be
selected using the wheel. The display shows channel numbers
as follows: c 1, ... c14, c15, c16.
3. Press any button to exit this menu.
7.4 MIDI controller
Each one of the 16 MIDI channels can transmit a lot of different
information –for example, note, keystroke strength and the so-called
controllers.
A controller is a command (e.g. instrument, volume, balance,
footswitch position) that in certain situations has to be defined very
specifically. A total of 128 different controllers can be set up.
There are several standards (0 = bank select, 7 = main volume) but
no fixed norm for the assignment of controllers to specific controller
numbers (0 - 127) exists. Different MIDI devices may react differently
to the same controller numbers.
To effectively control your FBQ2496, it is important to know which
controller numbers can influence individual parameters.
