Any way to reset BCR2000 other than reloading firmware?

Any way to reset BCR2000 other than reloading firmware?

2015-07-15 by orkanoid@...

hello people, my bcr2000 went crazy all of a sudden. some preset names became unreadable with strange characters. some encoders randomly have multiple leds lit, and moving some encoders affect other encoders' leds in the same row. pressing store button sometimes does a panic reset, or sends pitch bend on all channels (checked with midi monitor). page1 button sometimes jumps to other pages, or even changes preset.


i use the bcr2000 to control an access virus c and a novation ks. i mapped everything and created some presets some time ago, and all was working perfect until two days ago. suddenly everything messed up, can't figure out why. i didn't change any settings, i didn't even move the thing since i put it on my desk a couple of months ago.


all my midi gear is hooked up to a motu midi patchbay. i have a vst editor plugin for my access virus and it communicates with the virus via sysex and cc through the patchbay, so does the bcr2000. i am guessing maybe the sysex between the editor and virus somehow messed up the bcr2000 thru the patchbay by some corrupt sysex message. though this seems unlikely (different device id, different manufacturer id etc) i can't think of another reason.


i reloaded firmware 1.10 succesfully. after reloading firmware i checked with bcmanager if the factory presets were loaded and saw they were, and overwritten on my presets. but the problem is still there. does this mean i have a hardware problem? any other way to reset this device?


sorry for the long message, i tried to describe the situation as clear as i could. any help would be appreciated.

It sounds like hardware.

First step is to always replug all the connectors.

But really it sounds like the memory chip inside is not making a good connection.
It is mounted in a socket and then has hot glue applied, but perhaps it has come loose.
The hot glue is brittle and will just chip off.

There are pix in the our photo section here.

In the file section there is a guide opening the unit and getting off the sides (they have locking tags that you need to slide a steel ruler against to unlatch)

All the best

I have the greatest of respect for anything Royce says, but just before you go attacking the hardware, can you clarify. You said "i checked with bcmanager if the factory presets were loaded and saw they were, and overwritten on my presets".
Do you mean that you have re-uploaded your custom-made synth profiles to the BCR? Or that you saw they were still in place from before you had the problem? If the latter, hopefully you have them saved and could try uploading them to the BCR again, and see if that makes any difference. They must be saved in some form of on-board RAM so that could have been corrupted.
It's worth exploring all your options in software before you attack the hardware.

thanks for the replies. to clarify, i loaded firmware to overwrite my own presets with factory ones (i have backup of my presets as syx files anyway). then i checked with bc manager if the overwrite was successful and it was. but it didn't help fix the problem. i also reloaded some of my presets back today but no good. all the buttons and encoders respond, but not the way they are meant to be. for instance the 8 encoders at the very bottom row: when i move any of the encoders 2 through 8, an extra led appears around encoder 1, mimicking the movement of the other (2...7) encoder's led. same for other rows too, the leftmost knob led mimics the leds of other knobs on the same row.

maybe i should try to open it up and see if anything seems weird :l

See the cable connection in the same picture. ?
With the power OFF....

Pull out the cable (gently wiggle - the cable- if needed) and replace it back in the socket.
This can clean the pins enough to reinstate the connection.

You can also try it on all similar cables.
The keyway in the center of the socket means it can only go in one way.

This is the most common fault in electronics.
Second was ICs not making contact in their socket (same problem really).
If you press down firmly you might feel a little click as the IC reseats

For music stuff the next problem is usually dirt or wear in the encoder if it has been used a lot.

In old gear it is capacitors drying out. That is why everyone is re-capping their DX7 et al.

Not sure if you know this or have tried it, but if you take a wire (while unit is completely unplugged) and hold one end to ground and then simply drag it across ALL the rom chips (obviously you have to open the unit up and access the chips) legs, one at a time (and it can be rather quickly) it will "usually" discharge any bad or locked rom information that might keep the unit from proper power up enumeration...simply take one end of the wire to a ground screw and drag it across all the chip legs (try to keep it only on one leg at a time)...then put the unit back together and power it up...most of the newer chips have a register that when you reset a certain pin to ground they default to and in a burned in chip it is pretty simple to do this.

It is a fast way to see if you've "bricked it"
