BCR2000 resource packs

The zip files provided here each contain the following:

  • Overlays for SkinMan and ready to print.
  • Preset SysEx files for BC Manager or direct transfer to the BCR.
    • As it is not possible to tell the BCR how and where to include the MIDI channel number within the SysEx message, the byte containing the channel number must be hardcoded within the SysEx file. Refer to the ReplaceMIDIChannel_README textfile in the package for a search-replace string to change the MIDI channel to your needs.
  • BC Manager SysEx Definition File (if applicable)

You may use the content of the packages for your own purposes. For distribution, please link to this site.

Custom overlays for BCR

Proper overlays greatly increase usability of the device. You can visualize the controls much better as opposed to just text-labelling and thus bring you much closer to the device you are controlling with the BCR.

BCR2000_mKorg_ovly

The BCR2000 Templates document that you can find on the official downloads page contains simple overlays for control labelling. But I was looking for a way to create enhanced overlays that visualize the device being controlled rather than just labelling the controls.

Custom overlays with SkinMan

SkinMan is a freeware program for creating skins for audio plugins. I created templates for the upper and the lower sections of the BCR. SkinMan can be found here.
Download the SkinMan templates here.

The templates contain grouped elements of four basic types:

  • Background: The overall background of the overlay.
  • Cutouts: These should be left as they are, blank sections to be cut out of the printed layout. They represent the actual buttons and encoders on the device.
  • Labels: Editable primitives for the label background.
  • Label text: The text fields for each label.

To create your overlay, do the following:

  1. Download and install SkinMan
  2. Download the SkinMan Templates and open them in SkinMan.
  3. Design, hide, add or remove elements to your liking.
  4. When you´re finished, export the image via the File menu and print it out. I recommend to use good quality photo paper.
    Use DIN A4 (210 x 297 mm) as print size.

    alert Make sure to use borderless print setting, or the control cutouts will not fit!

  5. Cut out the cutouts (hence the name, right…) with a sharp cutter.
  6. For long term protection, laminate the overlay.
  7. Cut out the lamination foil again and you are done.

You may want to download one of the BCR sets below and use the contained overlay as an example.

BCR SysEx support

The BCR2000 SysEx capabilities are hardly covered by the official documentations and tools. I guess nowadays such controllers are mostly intended for use with software, to control DAWs and plugins. But they are equally ideal to control those 80’s to 90’s digital synths, which lack hardware controls but provide parameter setting via SysEx messages.

The BCR2000 is perfectly capable of that, but you have to know how to set it up. You can always use the learn function to assign a SysEx message to a control. If the SysEx message is simple, the BCR will perfectly recognize it. For proper setup however there is a perfect tool out there called BC Manager. It needs a while to get used to the interface, but you can edit and control every aspect of the device with it, send and receive data and manage multiple devices. A must-have for every BCR owner!

If you want more information on the SysEx capabilities of the BCR, check out the resources and links on the Mountain Utilities BCR/BCF page, too.

Behringer Neutron calibration

Do you also have the problem that sometimes the an oscillator of your Behringer Neutron is out of tune when you bypass its tune pot?
I had that a couple of times now and didn´t know what to do about it until today.
I assumed being driven by 3340 ICs the Neutron would not need any warm up time but maybe I am wrong. However during boot the Neutron calibrates the OSCs internally. I found that when you lock a Tune pot and the corresponding oscillator is out of tune thereafter, you should switch power off and back on so to force re-calibration. Mine was perfectly in tune after having done so.

Behringer VP1 LFO rate mod

Following a topic on a forum I modded my VP1 for slower sweeps of over one minute. Someone came up with the instruction where you put a large resistor between the center tap of the rate potentiometer and ground.
I did however not obtain a satisfactory result with the resistor values suggested by the other poesters. I found that for my purposes a value of 680k was best. So maybe you´ll have to do some experimenting as well.
Here´s what my installment looks like:

Midiverb II repair

I´ve had a broken Alesis Midiverb II lying around for quite some time now. Just recently I remembered that I´ve always liked Patch #28, even before I dove into ambient and drone. So I thought now was finally the time to open it up and give it a go, especially since not to long ago I aquired a Midiverb 4 from an old friend and thus had a working 9V AC/AC adaptor again which the Midiverb II also requires.

Symptoms

You´d plug in the power adaptor and nothing would happen, neither visually nor sonically. The unit was basically dead, or so it seemed …

Fault trackdown

It´s always a good start to make sure that all the supply voltages are there and within range. The Midiverbs rectify internally so I started at the power adaptor plug and made my way through the PSU unit. Power on all paths was present but at very low ratings. I unplugged it again and did some continuity measurements. I found a short circuit between the output and ground of the 7805 regulator. I took it out and found that it measured okay out of circuit so it itself couldn´t be the problem. I still had to replace it because the input leg simply broke with no real force applied,

The repair

So there was a short circuit on the 5V supply line. I measured continuity across all capacitors and marked al those that seemed short which I then soldered out. Basically I removed all ripple filter caps of the digital ICs. Subsequently I no longer measured a short circuit across the 7805. It turned out that two of the filter caps had shortened. I replaced those with 470pF that I had left over from the Opra 6 repair and put all the other working ones back in.
That was all it needed. Plugged in the adaptor and there it was up and running again.

Improvement

I noticed that the unit emitted a slight humn and a significant amount of noise when cranked up fully. I then remebered that the device has always been a little noisy. I then found that it might not be a bad idea to check whether the analog circuit could be improved upon. All opamps where LF347 and a little research revealed that the TL074 is compatibel and seemed to have better ratings. So I decided to replace all LF347 with TL074. I used sockets just in case that I where proven wrong and had to reverse it, which didn´t happen. I am quite stisfied with the improvement and really happy to have the unit back in working condition.

BCR2000 USB failure

If all of a sudden you are getting an error message on your Computer stating that your USB device failed then this is most likely due to worn out capacitors of the power supply.
I successfully got my device working again by replacing the two 1000uF electrolytics. The original ones where causing ripples on the supply voltage which lead to instable USB signals.
