Revised Firmware V1.4 for the DSP1124P with V1.3 ONLY!

**Sonnie** · **01-22-07, 08:42 PM**

Just use a drill and if necessary a hammer... leave it plugged up for an extra surge to burst it loose...

**jagman** · **01-22-07, 09:51 PM**

Is the firmware necessary if you don't use the midi jacks?

**brucek** · **01-22-07, 10:04 PM**

No...........

I was planning to pick up an 1124P from a local retailer. Am I definitely going to hit this bug with the midi (wanting to use REW to send filters/EQ to it), or does the issue only affect some units? Seems like this issue recently came up, so what changed that broke this (seems like many people in the past did not have this issue?)?

**01-24-07, 05:25 PM**

Can you update the title of this thread to say "revised Firmware v1.4 for V1.3 DSP1124P".

I'm new here, but if I read the threads correctly the V1.0-v1.2 DSP1124P BFDs don't have a problem between the Midi interface and REW do they? I have an older BFD and was thinking "oh " I need to upgrade the thing if I want to use a midi interface to store the filter values...

thanks
Dan

Hi Dan and welcome to the Shack!

Good idea... and done!

**lovingdvd** · **01-30-07, 02:44 PM**

I got my 1.4 chip but not in a hurry to install it. I've gotten used to manually entering the data into the BFD and figure I might as well save the $40 on the MIDI cable... still undecided though.

BTW, after I replace the chip will I need to reprogram all my filters in the BFD? Or is that stored in a different chip in the BFD?

One thing I found that eases the replacement is to remove the pin cable to the right. Just pop up the glue, remove the pin connector and then you have a "whole heaping passle" of room. I also use a hot glue gun to put a dab of glue on both connections.

Hi All!
First of all I would like to thank everyone on this forum for the effort you, guys made to solve this DSP1124P 1.3 MIDI problem!
Finally, I've received new eprom with 1.4 firmware (thanks Steph from www.Hobbyroms.com) and swapped out the ver 1.3 chip.
(I'm in Australia and it worked out very well for me, it took 10 days for the parcel to arrive)

Now I'm very happy to have my 1124 unit fully functional.

Regards,
Andriy.

OK, I tried to start a separate thread since it really is a different issue BUT did not get a definitive answer.
My question is: What is the difference from V1.0 to 1.1 to 1.2 to 1.3?
The difference from 1.3 to 1.4 is well documented here - I'll go out on a limb and say the only difference is that MIDI is enabled right???
But, I really would like to know of the differences from the other versions. Anyone?
TIA

The answer is no one knows..... Behringer fixes little things and they don't usually release what was done. We only knew this time since it was REW that uncovered a problem...

**02-14-07, 04:31 PM**

Recently, I also returned my DSP1124P to my vendor (still under 2yr warranty). Today, I received a new packet from Behringer Germany directly: An FBQ 2496. The DSP1124P does not seem to be produced anymore, so Behringer simply decided to exchange my device.

Of course, the 2496 has less presets than the old 1124P, but, still, a fair deal.

I should say it was a good deal. A higher price and far better specs.............

Hi Folks,

I have installed the V1.4 eprom from Hobbyroms.com in my DSP1124p.

I tested one of the MIDI commands so far- the Gain setting command, which is controller 16.
It is supposed to accept data values from 0 to 64 and sets the gain from -48 to +16dB on whatever filter is currently selected.
I manually put a filter in parametric mode at a freq of 1KHz and wide bandwidth. I was able to ramp the gain up and down on the filter using an external MIDI controller with scrollwheel. The results were audible and the display showed the gain changing.

I am satisfied that the MIDI functions are now working correctly and will now try out the Room EQ Wizard to see what it can do.

Thanks to all involved in making this fix available.

A local retailer is getting a couple of the 1124s in this week and I was thinking about picking one up. Will it have shipped with version 1.3 or 1.4? Any guesses? I really do not want to mess with the chip surgery.

**brucek** · **02-20-07, 10:34 AM**

Impossible to tell. Power up the units in the store and see what the version number is. Then you can make a decision. If you don't want to play with the prom, then get a 2496 instead.

Thanks -- beyond that, does anyone know if they are even shipping units with the new firmware, or all of these inventoried units that were built 8 months ago that are being released now?

As BruceK said, there is no way to tell except to go to the store and power up the unit while holding down the Filter Select button and read the Version # displayed. Those units could have been manufactured three weeks or three years ago. There is no way DEFINITE way to tell unless you physically verify it.

I just ordered one from ZZounds and got a 1.3 unit. Bummer...

Really not a big deal anymore. Just order the V1.4 firmware chip from Steph at http://www.hobbyroms.com and for $10 and for a some very easy effort, you are all set.
Remember, if you are not going to use the midi jacks, you don't need it. That being said, I could not live with that myself whether I was using the midi jacks or not...

**vfrjim** · **03-11-07, 09:23 AM**

I know that it was asked twice in this thread, but to me, it was never answered. If you have a Version 1.0, will it work with a Midi interface or would this need to be updated to V. 1.4?

Thanks

**brucek** · **03-11-07, 09:29 AM**

My understanding is that the earlier versions worked and somewhere along the line they messed it up. Someone else will have to verify....... hook up your cable and test it....send it a filter. If it takes, you're good...

I just updated the firmware in my DSP1124P, from ver 1,3 to ver 1.4 because I could not store the filter settings from the midi interface.

With my new update, I can now sore filter settings.

For you information I programmed a normal UV erasable 27C512 EPROM with the new firmware, instead of using the more seldom OTP HOC27C512 ROM, and that works very well too.

Boy am I glad I saw this thread! Just picked up a BFD from Guitar Center and was going to hook it up (and download filters via MIDI) tonight. Maybe not! Will hold my breath as I verify the version number at power on and hope to see 1.2 or earlier. If not, thanks to you guys I know what to do. Thanks in advance!

**04-17-07, 10:11 PM**

I bought one on the weekend (saturday) for $99.

midi didn't work.

went to the support web site and filed an online service request on monday

today I got a response saying v 1.4 firmware chip was in the mail.

I can't ask for better service than that.
