First commercially available in June 1979, it was introduced to compete with the Sequential Circuits Prophet-5, which had been successfully introduced the year before. About 800 units were produced with moderate success before the OB-X was discontinued in 1981, replaced by the updated and streamlined OB-Xa. The OB line developed and evolved after that with the OB-8 before being replaced by the Matrix series.

The OB-X was used in popular music by Rush (on Moving Pictures and Signals), Nena, Styx member Dennis DeYoung (used frequently from late 1979 to 1984), Queen (their first synthesizer on an album), Madonna for her debut album, Prince[3], a keen user, and Jean-Michel Jarre who used it for its massive 'brass' sounds.

Specification[edit]

The OB-X was the first Oberheim synthesizer based on a single printed circuit board called a 'voice card' (still using mostly discrete components) rather than the earlier SEM (Synthesizer Expander Module) used in Oberheim semi-modular systems, which had required multiple modules to achieve polyphony. The OB-X's memory held 32 user-programmable presets. The synthesizer's built-in Z-80 microprocessor also automated the tuning process. This made the OB-X less laborious to program, more functional for live performance, and more portable than its ancestors.

The 'X' in OB-X originally stood for the number of voice-cards (notes of polyphony) installed. It came in four, six, and eight-voice models with polyphonic portamento, and sample and hold. Even the 4-voice model was expensive at US$4,595. The entire range used 'paddle' levers for pitch and modulation, Oberheim's answer to the 'wheel' controls of the Prophet-5. Though these controls were never as popular as the standard pitch and modulation wheels, the philosophy was to mimic the motion of a guitar player bending the strings on their guitar. On most other synthesizers the pitch bend wheel was on the left, and the modulation wheel to the right of it; on the OB-X Oberheim placed them in the opposite relative positions. In addition to this unique configuration the polarity of the paddles was distinctive; the player would pull back on the pitch lever to bend the pitch sharp, and push forward to bend flat.

DiscoDSP released OB-Xd – a free emulation synth of the Oberheim OB-X, OB-Xa and OB-8 synthesizers.

Oberheim OB-X Emulation Synth

From DiscoDSP:

Oberheim Ob Xa Vst

The OB-Xd is based on the Oberheim OB-X. It attempts to recreate its sound and behaviours, but as the original was very limited in some important ways a number of things were added or altered to the original design. The OB-Xd was designed to sound as good and as rich as the original. It implements micro random detuning which is a big part of that sound. ... Like many synths of the OB-X’s generation, the OB-Xd has no internal effects so its sounds and textures can be greatly enhanced by the use of additional processing like chorus, reverb, delay, etc.

OB-Xd Oscillators

Synths

From the manual:

A mixer was introduced to blend the two oscillators and noise source which is much more flexible than the fixed levels of the original design. In the OB-X cross modulation (Frequency Modulation), OSC2 modulated OSC1. On the OB-Xd this is reversed: OSC1 modulates OSC2. Sounds created by sync and x-mod this way were judged more useful than the inharmonic results of the original modulation path. The Step switch allows for precise tuning by semi-tone steps. Note that disengaging this doesn't keep the pitch at the precise semi-tone step but resumes gradual pitch adjustment. The Bright control adjusts the clarity of higher harmonics. Detune of OSC2 only adjusts up from the basic pitch (the original was bilateral).

OB-Xd Filters

From the manual:

The original OB-X had a single 12dB/octave low-pass filter. The OB-Xd significantly improves on this design: it implements a Multimode 12dB/ octave filter like the Oberheim SEM module. Using the MULTI rotary control, you can crossfade between low-pass behavior on the complete left, to either notch (by default) or bandpass (using the BP switch) behavior at 12 o'clock, and high- pass behavior on the far right. There is also a 24dB mode which is activated by the 24dB switch. This mode is only low-pass, but the MULTI control now allows you to smoothly change the depth of the filter slope from 24dB/octave on the complete left, down to 6 dB/octave on the complete right.

How to Install

You can run the .pkg installer or:

  • Drag Obxd.component into Library / Audio / Plug-Ins / Components.

  • Drag Obxd.vst into Library / Audio / Plug-Ins / VST.

To install the presets, drag the 'Datsounds' folder into ~/Library/Audio/Presets/.
