New MIDI (Sys-Ex!) for Oberheim OB-SX

Rolf Meurer (a synth repair man and synth enthusiast who lives in Duesseldorf, Germany) developed a new MIDI interface for the Oberheim OB-SX. MIDIcontrol is simply attached to the 37-pin Oberheim port and that’s it! No extra modification required – the synth remains original!

MIDIcontrol turns the OB-SX in a fully programmable synthesizer (with some hidden functions) …

PLUG & PLAY – this is how it works:

  • Plug the OBSX MIDIcontrol into your DB37 connector at the rear panel of your OBSX
  • Load the mLab_MIDI-Control_BCR2000_C2_OBSX.syx file into your BCR2000
  • Connect your BCR2000 MIDI OUT to MIDI IN of your OBSX MIDIcontrol
    and you have real time access to all 32 Parameters of your OBSX

Finally, there are 56 user memories – edit and save your own sounds on the OB-SX! This is how it works on a Behringer BCR2000 controller:

“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 edited 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.”

“Es genügt, einen Ton schön zu spielen” sagte der Komponist Arvo Pärt im Jahre 2005. Diese Aussage ist ebenso einfach wie ich auch exzellent: Es braucht kein Meer an Tönen, denn entscheidend ist der Klang. Dass so mancher Vintage-Synthesizer der 70er und 80er Jahre teils unerreicht hochwertige Klänge liefert, steht außer Frage. Doch tatsächlich leben wir “heute” in einer nahezu perfekten Zeit. Einerseits hat man – mehr oder weniger – noch Zugriff auf die Vintage Analogen, andererseits wird auch bei Neugeräten die wichtige Komponente des hochwertigen Klanges wieder zunehmend berücksichtigt. Doepfer, Cwejman, Synthesizers.com, MacBeth, Moog, GRP, Studio Electronics, COTK, John Bowen und andere Hersteller bauen hervorragende Synthesizer, die den “Klassikern” in nichts nachstehen. All diesen (alten wie neuen) “großartigen” Instrumenten ist Great Synthesizers gewidmet. _________________________________________________________ In 2005 composer Arvo Pärt said: “Playing one tone really well is enough”. In other words, it is sufficient to play one tone 'beautifully'. I agree with that. All musical efforts are focused on the sound itself. Although I studied classical music (piano and drums), it’s the electronic sound that inspires me. Synthesizers are the epitome of new sounds and exciting tonal spheres. Today, many companies produce high-quality - excellent! - synthesizers: Doepfer, Cwejman, MacBeth, Moog, GRP, Synthesizers.com, COTK, Studio Electronics, John Bowen and others. It's their products I'm really interested in ... apart from Vintage Synthesizers, which I have been collecting for 20 years. Subsequent to our former websites Bluesynths and Blogasys, Peter Mahr and I have now created GreatSynthesizers. We hope you like it.
