BCD2000 + Traktor - MIDI Rules 
Saturday, October 6, 2007, 09:42 PM - Mac, BCD2000
I've uploaded a new experimental MIDI driver to the BCD2000 Download page that incorporates a jogwheel fix. This should make it possible to use the BCD2000 with Traktor, without the help of MIDI Rules (or Mandolane). I have included a simple .tks file to use in Traktor. So far the .tks supports the basic stuff and LEDs for the EQ buttons, but that's about it. If anyone manages to extend the functionality of the .tks please feel free to share it with the rest of us.

Update: I just finished uploading a more extensive version of the Traktor mapping file. This one re-introduces a number of features from the MIDI Rules ruleset. Most buttons are mapped one-to-one to Traktor features, however there are some exceptions.

You can browse your library by holding down the 'Phones Split/Master Out' button and using the jogwheels to browse the tree (left) or the list (right). Use the left 'Search' buttons to collapse/expand the tree, or the right 'Search' buttons to load the selected track to deck A or B.

Sync slave now maps to sync slave, instead of sync trigger. Both 'Back To Top' buttons are used as modifiers now. The left BTT button turns the Sync Slave button in a trigger for Sync Master. The right BTT button turns the Sync Slave button in a trigger for Sync. The left button also turns the Scratch button in a Tempo reset trigger.
I realize this is very complex and I could definitely use some ideas for improvements.

MIDI Rules 2007/08/09

Cycokraut pointed out to me that a new version of MIDI Rules is available. I added my GUI to it and put the image up for download right here (6.4MB).

More info...

BCD3000 users wanted (well... not anymore) 
Tuesday, June 5, 2007, 09:34 AM - BCD2000
Update: since we now have a way to use the BCD2000 natively in Traktor without MIDI rules, this post can be ignored now.

Do you own a BCD3000 or know someone who does? The reason I ask is, I'd like add a new feature to the BCD2000 driver that maps the BCD2000 controls to BCD3000 MIDI commands. The only problem is, I have no idea what those commands are. If someone could point me to a MIDI command reference or something for the BCD3000, that would be extremely helpful.

BCD2000 Driver FAQ 
Tuesday, May 15, 2007, 02:30 PM - BCD2000
I though it might be a good idea to post a FAQ here, since I'm often getting the same questions over and over. This should save you from having to read through all the comments :)

Q. The BCD2000 sometimes freezes after using the sliders. Is this a driver bug?
A. Unfortunately this is a hardware bug and I have not been able to find a software workaround. This seems to depend on your hardware setup. For example, I've found that my old PowerMac G4 constantly shows this behaviour, whereas I've only seen it once on my MacBook Pro. This is probably partially the reason why Behringer decided to give up on Mac drivers, and just released a revised unit (the BCD3000).
Things you can try to reduce the problem; try different a different USB port, don't use a USB hub.

Q. How do I use the audio output/inputs on the BCD2000?
A. For now, you can't. It's not supported by the driver and I'm struggling to find enough time (and willpower, I must admit) to work on it.

Q. How do I use the jogwheels in Traktor? It only moves in one direction.
A. Use the new drivers (with jogwheel fix), or alternatively follow the directions in the "BCD2000, Traktor, and the Mac." post.

BCD2000, Traktor, and the Mac. 
Sunday, January 14, 2007, 05:14 PM - Mac, BCD2000
Update: Check out the new tutorial which is a lot easier.

I finished packing up Cykokraut's MIDI Rules in a neat Mac friendly package. You can download it here (6.5MB). Source code will follow soon.

Update: It appears I left a rather embarrassing bug which would prevent the file dialog from appearing. A new release has been uploaded which should fix the problem. Thanks to Minotronic for pointing this out.

As promised, here's how to set up the BCD2000 for Traktor on MacOS X. Here's what you'll need:
- BCD2000 Driver
- Cycokraut's Traktor mapping files (pick any of the BCD2000-Traktor3* files, I prefer this one).
- MIDI Rules for Mac
- Plumstone (for PPC) or Mandolane (for Intel)

Step One: Close all MIDI applications. Install the BCD2000 driver per the instructions on the download page. Plug in and power up your BCD2000. It should now appear under "MIDI Devices" in the MIDI Setup utility that comes with MacOS X.
If it doesn't, something's wrong. Double check the driver installation (it should appear under '/Library/Audio/MIDI Drivers' ). Try restarting your Mac. If that still doesn't fix it, drop me a note and we'll try to sort it out together.

Step Two: install Mandolane / Plumstone
This is probably the most tedious bit. This adds the MIDI support to Java that Apple forgot to implement. Unzip the package, and copy 'plumstoneserv.jar' for Plumstone, or 'libMandoMidiJNILib.jar' and 'libMandoMidiJNILib.jnilib' to '/Library/Java/Extensions'.

Step Three: enable IAC
Open Audio MIDI Setup in Applications/Utilities, under "MIDI Devices" double-click "IAC Driver". Make sure "Device is online" is checked and click Apply. Close Audio MIDI Setup.

Step Four: configure Traktor
Launch Traktor and open the Preferences. Under Hotkey & MIDI Setup > MIDI Interfaces enable the 'Apple Computer, Inc. IAC Driver Bus'. Make sure the BCD2000 is disabled.
Under Hotkey & MIDI Setup > MIDI Setup click 'Load'. Select the appropriate .tks file from the Traktor mapping files and click Open. Apply changes and leave Traktor open.

Step Five: start MIDI Rules
Launch MIDI Rules.app. Click 'Select' and find the .drl file from the Traktor mapping files and click 'Open'. Select the BCD2000 as your MIDI input. Click the '+' button until you've got two outputs in the list. Select the 'Apple Computer, Inc. IAC Driver Bus' as Output 1, and the BCD2000 as Output 2. Finally, click 'Run'.

At this point you may get a license reminder from Mandolane. If so, simply click 'Yes'. After that, the LEDs on your BCD2000 should all simultaneously light up for a second, and you should be able to control Traktor through your BCD2000. If for some reason it doesn't work, try launching Console.app (in the Utilities folder) and look for clues.
