Power Supply

This MIDI-Interface needs an external power supply (not included). The power supply should output 9V DC where the center pin = (+). If you don't like to use an external power supply, you can supply The magicBox from your Synthesizer by doing a simple modification.

Plug & Play

Installation is much easier than any other MIDI retrofit kit.
We leave your Oberheim synthesizer completely untouched.
Simply plug the magixBox into the Oberheim COMPUTER INTERFACE & play.

MIDI communication

MIDI IN to the Oberheim Synthesizer

MIDI OUT from the magicBox

1. MIDI SysEx dump

MIDI cc 107 (value 127) causes The magicBox to send a SysEx Dump of all 56 user memories to MIDI OUT. So you can backup your sounds. You can recover them by sending the SysEx file back to The magicBox. This will replace all of the 56 user memories automatically.

2. PARAMETER FEEDBACK

After a MIDI Program Change or a Program Load, the magicBox sends the current program parameter values to MIDI OUT. When a BCR2000 or another controller (which can process parameter feedback) receives such a message, It updates its encoder and shows the result with its LED bar graph. Now you know exactly where you are and you can visually edit your program in relation to the current settings. To avoid MIDI feedback loops with a BCR2000, use the Stand Alone-Mode S-3 by pressing EDIT & STORE at the same time. Now dial the left encoder in the top row until the display shows S-3. Then, press the EXIT button to complete the process.

Successfully tested MIDI controllers

Other generic MIDI controllers should work, as long as they can handle ParameterFeedback.

How to Setup a BCR2000

  1. Set your BCR2000 to receive MIDI data via the MIDI input.
    Hold down the EDIT button and press the STORE button.
    Use the first encoder in the top row to choose S-3.

  2. Make sure your BCR has the correct SysEx ID by using the 5th rotary encoder in the top row
    and set it to ID number 1.
    At least press the EXIT button.

  3. Now send the SysEx file to your BCR2000.
    Successfully incoming SysEx data is shown in the display as a circular movement.
    The BCR first saves the incoming data in a temporary memory area.
    Before this data can be used, it must be saved in one of the 32 BCR2000 PRESETS.

In order to do this,

  1. Press the STORE button, (the store LED blinks).

  2. Use the PRESET cursor keys to select a preset location.

  3. Press STORE again.

That's it.

 

User Memory management

Example Copy, Edit and Save movie

Use the encoder in the lower left to select a preset (1..56).

Use the encoder at the bottom right to select a user memory (1..56).

For example, load the preset No. 33 by dialing the encoder at the bottom left until the display shows 33.

Then press the LOAD button.

The preset No. 33 is now loaded and can be edited as required.

To save your changes in one of the 56 user memories, dial the encoder in the lower right to select a user memory location.

Then press the SAVE button.

If you are not using a BCR2000, please refer to the MIDIcontrol details below. This should help you configure other MIDI control devices.
