FEEDBACK DESTROYER PRO DSP1124P

The fifth page of the MIDI menu shows the “Store Enable” flag represented by a capital “S” in the DISPLAY.

Available values are “0” and “1”. If set to “1”, the FEEDBACK DESTROYER PRO receives controller 18 as a

direct save command, i.e. the current settings will be stored without further confirmation in the preset number

that corresponds to this controller value. If set to “0”, the DSP1124P ignores all incoming commands referring

to controller 18.

+

ATTENTION!  Store  Enable  mode  has  been  designed  to  transmit  several  presets  as

conveniently as possible from an external PC to the FEEDBACK DESTROYER PRO. In this

mode, it is possible that stored presets will be replaced or altered if controller 18 messages are

sent via MIDI! We therefore recommend that you disable this mode as soon as the intended

data  transfer  has  been  completed.  During  power-up,  this  mode  is  automatically  disabled

(mode “0”).

On the sixth, and presently the last page you can access the “System Exclusive” functions, which is indicated

by a “d” (= dump) in the DISPLAY. To the left of this “d”, you can see a “0” if no sys-ex data can be received or

transmitted. When you enter mode “1”, the DSP1124P will be able to receive sys-ex data. In mode “2”, the

DSP1124P is ready to dump its entire memory contents with all parameter settings to an external MIDI storage

medium. Start your sequencer software, and press the STORE key. To load the data back, select mode “1”,

and start your sequencer software to restore the settings in your FEEDBACK DESTROYER PRO.
If you press the IN/OUT key again on the sixth page, the FEEDBACK DESTROYER PRO quits MIDI mode.

You can also use any other key to leave the MIDI setup menu.
The full-featured MIDI implementation of the FEEDBACK DESTROYER PRO allows for easily integrating the

unit into any MIDI system.

s

MIDI IN

All MIDI data sent to the DSP1124P (sequencer, MIDI foot controller, etc.) are received via the MIDI IN jack. For

example, if you wish to use the DSP1124P as an effects device for your guitar rack, you can connect the

MIDI IN jack to a MIDI foot controller that allows for selecting program presets. If your rack includes another

MIDI effects device, the data sent from the MIDI foot controller can be passed on to that device through the

MIDI THRU port of the FEEDBACK DESTROYER PRO.

s

MIDI THRU

The MIDI THRU jack is used to loop through incoming MIDI data, i.e. any controller data received at the MIDI IN

of the FEEDBACK DESTROYER PRO will be transmitted via the MIDI THRU jack to other MIDI devices/

instruments.

s

MIDI OUT

The MIDI OUT jack allows for transmitting MIDI data that originate from the DSP1124P.
The FEEDBACK DESTROYER Design Editor software enables you to control the DSP1124P from an external

PC. What is more, you can use the FEEDBACK DESTROYER PRO to control the editor software, so that both

units communicate with each other. Download the editor free of charge from our web site at www.behringer.com.

10. INSTALLATION

10.1 Audio connections

As a standard, the audio inputs and outputs on the BEHRINGER FEEDBACK DESTROYER PRO are fully

balanced. If possible, connect the unit to other devices in a balanced configuration to allow for maximum

interference immunity.
