Repairing a Behringer BCF2000

My beloved Behringer BCF2000 midi controller was already broken when I bought it used over 10 years ago. The unit has 8 motorised faders and 8 rotary controllers with LED rings so it’s great to use with midi feedback and it’s a good bang for the buck. I was surprised to see that this model is still sold on-line despite the fact the Behringer has put out a new model.

The guy that sold this unit to me didn’t tell me that fader one didn’t move by itself and something was loose inside the case. Now, after my successful repair of my wife’s midi keyboard I’ve gotten hubris and think that I can repair anything. Well, at least I can repair simple stuff that doesn’t contain any advanced troubleshooting.

I was smart enough to see if there was any disassemble manuals on-line and I found a PDF document that detailed how to tighten up the belts for the motorized faders. Sadly there’s quite a few steps to reach the faders. Once there I realised that fader one’s belt and one of the screws had come loose and it was really easy to attach them again. When I lifted the panel covering the faders the belt from fader eight came loose too but it was as easy to fix as fader one.

While I was inside the unit I figure I could tighten up the fader belts as described in the PDF. Unfortunately I tightened three of them too much so I had to go unscrew everything once again to loosen the tight belts. This time I did’t put all of the pieces back before testing which was good since I also needed to put some hot glue on the ribbon cable connectors so that the cables stays in place.

By this time I had figured out that I wanted a nice way to show off the working motorized faders. I could probably have done this quickly in a DAW but I wanted to do it in Vezér, a MIDI/OSC/DMX timeline app. I quickly programmed the eight waves seen in the video.

Right before putting back the two side panels I noticed that the holder for the power button had came loose from the case. I epoxy glued that back before doing the final assembly. Now the machine is in better shape than ever.
