Hi Christian!
I was replacing between BCR & BCF the upper board, the CPU board (replacing both OS chips obviously), tried to replace LCD display… Nothing of this was successfull. Always with the same failures: some buttons does not activate at first push, or changes randomly the sequence parameters, or jumps to other buttons without push them, etc… (specially MIDI CTRL ALPHA & BETA, CLOCK, and MIXER)

I’ll send you soon a small video which is seen all this at the e-mail adress.

But today I made a last try, and I think it’s definitive. My BCR is not working well, maybe a serious breakdown. I reinstall the original Behringer’s BCR OS and does not work, there is no lights on LED rings when turns any encoder, and the push buttons rests always OFF, it can’t push to ON. The preset buttons also jumps randomly to other presets (1 & 2) or activating one of 4 “track buttons” with no sense, and on LCD sometimes appears “init” message when try to change.
Resume: with BCR OS installed there is no lights even moving knobs or buttons, only display lights up…

I think should be better buy other BCR (and cross my fingers)

definitely there is no way, does not work. I tried lots of combinations and replace lots of parts, even the CPU board. I think there’s no easy solution, and i don’t want to spend more money in to another BCR… it’s very frustrating to me.

It’s a shame, I really love the idea of this sequencer, and it’s an ideal tool for my music.

That was no success, I tried to replace the led display but the problem persists.

I think I’ve a final solution. The last try to fix it, and I think maybe it’s a logical solution: change the CPU board between BCR and BCF (my BCF works well) and then replace the OS chip. Both CPU boards are the same…

Maybe my BCR CPU board are causing this problems, maybe don’t work correctly.

This are my last attempt to fix all the errors on BCR, if it does not work I don’t know what to do (I’m desperate…). I think it seems a locical solution.

Thanks again Christian for your support and comments!!

I’ll post the final result this week

Thanks Cristian!

I try to replace the upper board this weekend, if it does not work or is incompatible I’ll make a second try removing the BCR display and mount the new one from BCF… Let’s see

I post the results here when I finishing.

Thanks again!

From this week I’m a new Zaquencer user. I just make a few tests in past two days (note pitch, seq length, steps number…only basic). And I detected this weird things probably described as a multiplexer failures or something like that.
I saw the “Repairing a BCF” from Ricardo Dias and he tells finally the problem may be the display segments. In my display I do not notice any failure but I’m not sure at all.
The problem I have are in 3 or 4 buttons:
- Clock Divider (14): No active when pushing normally and jumps to other button activation. But you can activate it if you hit them a little bit hard and no causes a strange or weird “artifacts”.
- MIDI Ctrl Alpha and Beta (6 & 7): wow! here is the bigger failure… It’s impossible to get access to those functions. It jumps to other buttons when pushing every time, and it goes beyond, it causes dramatic changes in ALL sequence parameters and MIDI controls randomly (pitch, aftertouch, prog change…all), and the sequence becomes in a “something” impossible to work.

So, I’ve a question for repair it. Are the entire upper board compatible between BCR and BCF? Can I replace it the one for the other “as is” and fix all the multiplexer errors in whole BCR system?. I don’t use my BCF and maybe can use it for parts.

Thanks!!

(sorry for my english… I try to explain better as i can)
