The Ultimate Analog Synthesizer. The fully programmable Oberheim OB Mx brings all the power and glory of the analog synthesizer to new levels of stability and reliability via the use of modern components and technology. Fully decked out with up to the minute MlDl implementation, the OB Mx is the analog synth for the '90s and beyond.
The OB Mx is shipped as a two voice unit, and is easily upgraded with user installed Two Voice Cards to a maximum of twelve voices. Each OB Mx voice features: 2 Voltage Controlled Oscillators, 3 Low Frequency Oscillators, 4 Envelope Generators, The Classic Oberheim Voltage Controlled Filter, The Classic Mini-Moog Voltage Controlled Filter (as a bonus, both Filters are self oscillating and track over eight full octaves!), a Final Mix Module using the Oberheim S.E.M. Filtering, plus Portamento, Sample and Hold, FM, oscillator Sync and much, much more. It is this unique combination of filters, combined with an abundance of envelope generators and LFOs that allow the OB Mx to create virtually any sound in the analog palette.
Memory is provided for 128 user defined sounds, and 128 sounds are in permanent memory from the factory. Additionally, 128 user memories are provided for Multi-Sound Programs, as well as 128 factory Multi-Sound Programs.
The front panel of the OB Mx is always live. Grab a knob, twist it, and the unit responds. Real-time control over every element of sound creation offers a level of expression not available on any other synthesizer. Each outlined area on the front panel represents an individual synthesizer "Module". Each Module is equipped with a select button that displays every parameter in the generous 23 Line x 40 Character Backlit display. All settings are displayed in Hz, milliseconds, half-steps, percentages, or other relevant increments. Even the LFO wave shapes are displayed graphically.
Extensive MlDl implementation supports System Exclusive for saving and loading OB Mx patch data. Every knob on the front panel can be controlled via real time MIDI, either in performance or from a sequencer. The Oberheim "Matrix Modulation" section provides "Software Patch Cords" that allow Modules to be connected together for extensive modulation effects.
Various Key Assign modes allow Voices to be stacked up for a sound as "fat" as you desire. and will also control voice allocation and envelope re-triggering.
Programmable Tuning Tables allow the OB Mx to expand beyond traditional western 12-tone tunings. Each and every key is assigned its own pitch and deviation from that pitch.
The back panel features Left and Right Stereo Outputs, as well as an individual output for each voice. These individual Outputs are T/R/S insertion jacks that permit each voice to be processed individually, and still appear in the stereo mix.
As a Multi Timbral unit, the OB Mx can play six different parts simultaneously. Each part can be programmed for a particular Zone, MlDl Channel, Bender Range, Transpose, Key Assign Mode, Tuning Table, Pan amount, Attenuation and Volume.
With a legacy as old as the industry, the OB Mx incorporates three of the top names in analog synthesis. Oberheim brings over twenty years of design innovation and technical leadership to the OB Mx. Add to that the original Mini Moog "ladder" filter circuit. and a design team headed by synthesizer visionary Don Buchla, and the OB Mx is sure to please anyone who has a fondness for the warmth and fullness of an analog synthesizer.
