Top Row Faders Exhibit Jumpy Behavior

    I am curious about the behavior of the top row of faders. They seem prone to somewhat erratic action when turning them, with values occasionally going way up or down. It's almost seems as if there is another stream of conflicting data affecting them. This occurs thoughout their arc, BTW.

    It occurs at either 7 or 14 bit, with virtually any resolution settings (single or stepped), etc.... I have 2 BCRs and it does this on both of them.

    This does not occur with the lower 3 rows, whereas, the top row, at the same settings, will exhibit this nonlinear behavior. I have the lower 3 rows set to a multi-stepped resolution and they're smooth as glass. It's great to be able to do slow and precise changes, then turn the knob quickly to reach the extremes.

    For the moment, it seems that a very low resolution of 32 is the most stable. It's a bit tedious, though. Any thoughts?

 

Thanks.

    Looks like I've answered my own question. It appears some of the upper rotaries are failing. I imagine this is a function of the integrated switch in the pot. The assembly is more complicated and less robust than the lower 3 rows, which don't have the integrated switch.

    The top row of rotaries on my 2 BCFs. which have little to no use, work fine on the same settings. Only rotaries 1,2 & 8 on the BCRs (which have had the most use as switches), are failing. I don't imagine there's a cost effective solution from Behringer for replacing select pots..... Probably cheaper to buy 2 new BCRs and avoid using the dual function of the pots.

   

    Consider this a cautionary note for others: go very easy on that top row of rotaries/switches.

    Good news. I'm an idiot. I was tired and should have thought of this: contact cleaner! The unit works as new. A little bit of cleaner and exercising the pots cured the problem. My apologies to Uli:) Lesson learned.

One thing is clear: (electro-)mechanically the encoders (particularly the push encoders) of the BCF and BCR are not exactly first-rate.

Over the years I've read quite a few horror stories about problems in this area. It would be great if we could simply buy a couple of separate encoders for a few bucks, but (if I'm not mistaken) that's not possible.

On my BCR some of the (push/simple) encoders exhibit significantly less resistance than the others. I tend to avoid assigning functions to the low-resistance ones, knowing that the difference in resistance tends to distract me once every while...

I've also found that it can be hard to press certain push encoders without also turning them a bit; depending on the assignments one has made, this could be very dangerous...

Hi Mark:

"It would be great if we could simply buy a couple of separate encoders for a few bucks, but (if I'm not mistaken) that's not possible."

    I believe you can buy the Behringer encoder from Full Compass. http://www.fullcompass.com/prod/284071-Behringer-Y32-30030-05278

"I've also found that it can be hard to press certain push encoders without also turning them a bit; depending on the assignments one has made, this could be very dangerous..."

    Absolutely true. My tendency in mapping plugs is to avoid using the "push" portion of the encoder. My recent experience gave me quite a scare. Even though it turns out that the functionality is actually fine, I'm still a bit leery of their durability.

    I use 2 BCRs and 2 BCFs. This weekend, I wiped the BCFs and created 2 new Generic Remotes with them, in Cubase. The flexibility I've worked out with the BCRs is now available in the BCFs. Frankly, this blows away the Mackie Control emulation in Cubase. It also gives me a ton of newly available siwtches/buttons, which provide options to reduce the need for the top row push switches.

    This setup is a revelation. Hitting a preset, I can have one of the BCFs devoted to all the electric guitar tracks and their group fader, or any other channel/group combinations, for that matter. Default use is for the 16 busses feeding the 2-buss. Having the visual feedback in Cubase, displaying the name of the preset really helps, too. I wish I'd done this sooner. The Mackie emulation is crude and limited, in comparison.   

    One last question: I find that the first time I use some buttons in a session, I have to hit them twice. This is never the case with the preset buttons, just others. It there a setting to modify this behavior?

 

 

Thanks again!

Interesting that Full Compass is selling the "Behringer Y32-30030-05278 - Rotary Encoder for BCF2000 and DJX750".
(Side-note: why don't they mention the BCR as well? At least I assume the BCF and BCR's push encoders are the same...!?)

When I wrote that I thought the BCF/R encoders were not available, this was because of a discussion in the BC2000 Yahoo forum about encoders about two years ago. I didn't pay close attention at the time, but I remembered the conclusion as being that the Behringer rotaries as such were not on sale anywhere (although people did find rotaries that came close) - but maybe my memory was faulty.

Anyway, thanks for the link!

Disregard. I determined the proper settings. Buttons work as they should.
