SYSEX COMMANDS FOR BEHRINGER ULTRA CURVE PRO DSP 8024
Compiled by Adriano Ficarelli Jr - ADRStudio.com
03/27/2003 - Rev.13
Note:
The information below I obtained by dumping the communication between DSP8024 and my computer.
Discovering one by one, and figuring out how they work. Some at bit level.
As you know, Behringer original manual does not have any information about SYSEX, and BEHRINGER
support does not provide this information too.
All commands work fine, but some are missing. The most important for me that are missing: the reset of
HOLD Curve of RTA, and, switch between LEFT and RIGHT on EQ display.
The reset of RTA can easily be simulated by switching the input to MICRO and then back to L+R. If no
Microphone, it zeroes the Hold. Switching the Decay Time also resets the Hold curve.
Others missing commands that should be very useful are switch to the LEVEL METER and to FEED BACK
DESTROYER (or Parametric EQ). They probably it will never work because, unfortunately, inside these
screens, the SYSEX receive is disable, so nothing change when you send SYSEX commands, and you can't
send a command to return to the EQ main screen also. Only changing the Operating System
can make it possible (it means write and change EPPROMs, etc.).
Special thank's for Florian Bömers ( www.bome.com ) for the tool SendSX.

TIPS:
You can combine two or more commands. The string "F0 00 20 32 00 0E" is the header for sending
commands to DSP8024. This way you can send one header followed by the strings of the commands you
want to send, and put "F7" to finalize the line.
See examples below:
1. Changing EQ master volumes level of both channels at the same time and synchronized ( volume
command is "11 s0 xx" ):
F0 00 20 32 00 0E 11 00 xx 11 20 xx F7 where xx is the desired level.
2. Put all frequencies at level zero (frequency level string is "10 sr xx") :
"F0 00 20 32 00 0E 10 00 20 10 01 20 10 02 20 10 03 20 10 04 20 10 05 20 10 06 20 10 07 20 10 08 20 10
09 20 10 0A 20 10 0B 20 10 0C 20 10 0D 20 10 0E 20 10 0F 20 10 10 20 10 11 20 10 12 20 10 13 20 10 14
20 10 15 20 10 16 20 10 17 20 10 18 20 10 19 20 10 1A 20 10 1B 20 10 1C 20 10 1D 20 10 1E 20 F7"
Note that you can include the string "11 00 20 11 20 20" just before the "F7" so you can zero the master
volume at the same time. Remember that 20h is the middle, means zero dB.

REQUEST DATA
The most simple way to request data from DSP 8024 is just send the header "F0 00 20 32 00 0E" or "F0 00
20 32 7F 0E" followed by "70" and by the parameter number you want to request and close the
string with "F7".
Ex: To request the level of Noise Threshold just send:
F0 00 20 32 00 0E 70 15 F7 (or F0 00 20 32 7F 0E 70 15 F7)
you will receive the string:
F0 00 20 32 00 0E 15 xx F7 where xx will be the value of Noise Threshold.
Where you have more than one value for a parameter, follow the rule but add the others variable to the
string.
Ex: To request the right master level of the Graphic equalizer send:
F0 00 20 32 00 0E 70 11 20 F7
you will receive the string:
F0 00 20 32 00 0E 11 20 26 F7 when the master right level is set to +3 dB (26)
You can also combine more then one request in only one string, with the following string:
F0 00 20 32 00 0E 70 15 70 11 20 F7
you will receive:
F0 00 20 32 00 0E 15 xx 11 20 yy F7 with the Noise Threshold (xx) and right level (yy).
