OB-SX MIDIcontrol REV.3C

is a plug & Play MIDI-Interface for The OBSX 37Pin COMPUTER PORT.

This interface transforms your OBSX into a fully editable Synthesizer.

All parameters are editable in Real Time via MIDI controller change messages.

A ready to go SysEx setup file for The Beringer BCR2000 is available here.

If you prefer to use an iPAD, download the TouchOSC Layout here.

or download the TB MIDI STUFF (TBMS) file for iPAD here.

A Video Demonstration is available here.

Orders are welcome here!                 The price is 398,- €

MIDI I/O 

The interface needs an external DC power supply (not included)
The power supply should output 5…9V DC where the center pin = (+)

If you don't like to use an external power supply (as I do) you can supply your interface from the OB-SX by doing a little OB-SX modification.
In this case please let me know when you place your order, and I'll ship your interface with an internal jumper set to be supplied by your modified OB-SX.

Plug & Play

Plug the OBSX MIDIcontrol into your DB37 connector at the rear panel of your OBSX
and you have real time access to all 32 Parameters and much more.

Additional features:

MIDI NOTE ON / OFF 6 voice Polyphonic or UNISON
PITCH (+/- 1 tone)  in half tone steps does not sound really bad, better than nothing. 
PROGRAM 1 ... 56 These are the 56 OBSX ROM presets. (supported by this interface, also if your OBSX has less than 56 presets)
PROGRAM 57 ... 112 These are 56 additional user memory locations (you can copy, paste, edit and save).

Hardware support:

1. Behringer BCR2000 support with parameter feedback function.
2. TouchOSC support for iPAD.
3. TB MIDI STUFF (TBMS) supprot for iPAD.
4. All generic MIDI controllers

MIDI OUT hardware:

There is only one MIDI Jack, but if required, you can use the free MIDI jack pins 1,2,3 for the MIDI OUT functions.
All you need is a MIDI Y-Split cable, and here comes the pin out:

BCR2000

Use such a MIDI Y-Split cable to connect MIDI OUT to the BCR2000 (or iPAD) MIDI IN
and connect MIDI IN to the BCR2000 MIDI OUT B/THRU (or to MIDI OUT of your iPAD MIDI-Interface)

MIDI OUT functions:

1. MIDI SysEx dump

CC 107 (value 127) tells the interface:
Send a MIDI SysEx dump of all 56 user memories to MIDI OUT.
So you can backup all your programs.

Of course you can send back these SysEx files via MIDI to your interface.
This will replace all your current user memory locations automatically.

2. PARAMETER FEEDBACK
After a MIDI Program Change or a Program Load, the interface sends
the current program parameter values to its MIDI OUT pins. If a BCR-2000
or an iPAD receives such a parameter feedback, then a BCR-2000 as well an iPAD
will display all parameter values. Now you know exactly where you are and you
can visually edit your program relatively to the current settings.

To avoid MIDI feedback loops using a BCR2000, set the BCR2000 Global setting to S-3 by pressing
EDIT & STORE, then dial the upper most left encoder until the display shows S-3
and at least press the EXIT button.

HOW to load the SysEx Setup into your BCR2000.

1. check if your BCR2000 has the right SysEx ID.
While holding down the EDIT BUTTON, press STORE.
Use the upper row 5th rotary encoder to set the ID to number 1
Press EXIT to quit this menu.

2. send the sysex file to your BCR2000.
After that, the BCR2000 holds the sysex file in a temporary memory area.
Before you can use it, you must STORE it to any of the 32 BCR2000 PRESET location.
To do so:

3. Press the STORE BUTTON once. (The STORE LED then will blink continuously)

4. Now use the curser buttons to select a BCR2000 preset location of your choice.

5. Then press STORE again.

That's it.

Presets & Memory management with the BCR-2000:

Use the lowest most left encoder to select one of the OBSX presets 1..56
and use the lowest most right encoder to select one of the flash memory locations 1..56
The lowest left button is the Load button and the lowest right button is the save button.

Example copy, edit and save:

Load e.g. the OBSX Preset 33 by dialing the lowest most left encoder to number 33 and press the LOAD button.
The OBSX preset number 33 now has been loaded and can be edit as desired.
After that you can store your modifications to any of the 56 memory locations
by dialing your desired memory location number with the lowest most right encoder and press the save button.

If you don’t use a Behringer BCR-2000,
here is a controller list of the programming encoders and switches:
This will help you to configure these functions for other MIDI units too.             
         

CC 85 (value 1..56)                           Select a preset location 1…56
CC 86 (value 1..56)                           Select a user memory location 1..56
CC 87 (value 127)                             Load this selection into the OBSX  edit buffer
CC 88 (value 127)                             Save the current sound to the selected user memory location

Also available is a setup for iPAD TB MIDI STUFF (TBMS).
