I know this is an old thread, but I still think it makes sense to share my experiences. I have a new FBQ2496 (2024-02-06) and it works perfectly if you depend on really low latency (monitors in the studio where instruments are played in real time). There has been a small bug which has caused the...

Hi! I've tested some random frequency in ranges where I've previously seen deviations and now the MIDI data being sent looks completely correct :) I'm very glad you fixed this. The FBQ2496 is an excellent and very affordable solution for those of us who need, low latency (max 1-1.5 ms), +4...

Yes, I have already done that. But I am posting it again in JSON format this time. The columns of the inner array are: 'CENTER_FREQUENCY_HZ, 'FREQ_COARSE_CC_VALUE', 'FREQ_FINE_CC_VALUE' Regards, /Michael

OK, I'll try to help as best I can here. But because neither English nor maths are my first languages, I find it difficult to make myself understood here. The reason I started looking into this was because I found that when I send MIDI with REW, the center frequencies often end up a couple of...

Thanks for your reply. I interpret it as the status is WONTFIX regardless of whether the FBQ2496 gets the correct settings or not. But it is not a serious problem. As a workaround, I have written a python script that automatically parses the exported filter settings text file from REW and sends...

Hi! I started doing the time consuming manual testing procedure. And with four filters tested and 50% failed tests, I'm pretty sure already that REW is sending the wrong MIDI CC values and possibly not handling the set frequency scale of the FBQ2496. And in terms of my experiences so far with...

Just looking at the MIDI values passed in from REW for MIDI CC 46 and it makes me suspicious. Center frequency in rev 41.8, CC 46 sent value 7 (about in the middle for step 1), fine. Center frequency in rev 46.3, CC 46 value 15 (on the higher bound for step 1). It doesn't look consistent. If I...

But if someone can look at my previously attached file fbq2496-freq-to-midi-cc-table.txt and explain the selectable steps via MIDI mathematically, that would be more than welcome. The manual says it's a logarithmic allocation of frequencies but it doesn't look quite consistent in my findings...

Excuse me for rambling on, I measure and report back with the facts. Regards, /Michael

But what about the algorithms for choosing the nearest selectable frequency step via MIDI? Do you use your own lookup table (MEASURED_FREQ,FREQ_COARSE.FREQ_FINE)? I can't really understand how my FBQ2496 ends up several steps wrong. But if Behringer has made a really crazy mistake with how they...

OK, I didn't notice any problems with the MIDI transmission. It was completely repeatable every time. The same MIDI values resulting in the same values at the display.

OK, interesting :) Will be interesting to see if what REW sends via MIDI for a given center frequency is completely consistent with how my newly purchased FBQ2496 measures. I should have time to measure it before next weekend. If so, it would be good to clarify that somewhere. That the FBQ2496...

OK I understand. But It looks like there are bigger differences then the precision between what the display shows and and what REW says the center frequency should be. Maybe I'm wrong but, you can't assign any other frequencies via MIDI then the steps that are available as selectable CC values...

And, sorry, the same goes for available bandwidth steps (CC 15). Regards, /Michael

And I forgot, MIDI Monitor confirms that REW is sending all required MIDI CC values. But the mapping between available frequency steps and values for FREQ_COARSE (CC 14) and FREQ_FINE (CC 46) seams to not to be correct. Regards, /Michael
