The Oberheim OB-X8 is a powerful analog polyphonic synthesizer that combines the best features of its predecessors - the OB-X, OB-Xa, and OB-8 - into a single instrument. This 8-voice synthesizer boasts a pure analog signal path, delivering the warm, punchy Oberheim sound that has been featured in countless iconic recordings.

The OB-X8 comes in two versions: a keyboard model with a 61-key FATAR velocity- and touch-sensitive keyboard, and a compact desktop module. Importantly, the desktop module features an identical sound engine to the keyboard version, ensuring no compromise in sound quality. Both versions offer an all-analog signal path with discrete VCOs, VCAs, and filters, providing the classic Oberheim tone.

At its core, the OB-X8 features two discrete SEM/OB-X-lineage VCOs per voice, offering saw, square/pulse, triangle, and noise waveforms. It includes both discrete SEM-lineage VCFs for authentic OB-X-style tone and genuine Curtis filters for the bold character of the OB-Xa and OB-8. The envelope responses are meticulously modeled to match each OB model.

A standout feature of both versions is the knob-per-function interface, providing immediate access to virtually all the synth's parameters. This allows for intuitive and precise sound design, whether you're tweaking factory presets or creating your own unique sounds from scratch.

While the desktop module lacks the keyboard and pitch/mod paddles of the full-size version, it retains all other functionalities. This includes the full-featured arpeggiator and the keyboard split & double functionality, making it fully operational when connected to your preferred MIDI controller.

Both versions of the OB-X8 include over 400 factory programs, including the full set of sounds from the OB-X, OB-SX, OB-Xa, and OB-8. The recent OS version 2.0 update has further enhanced the OB-X8's capabilities, adding features such as binaural mode for true stereo operation, simultaneously selectable waveshapes for each oscillator, a new 4-pole low pass filter type, and support for MPE (MIDI Polyphonic Expression) for nuanced control over individual notes.

The OB-X8 also offers extensive connectivity options, including stereo and mono outputs, various control inputs, MIDI connections, and USB. With its combination of classic analog sound, modern features, and expressive capabilities, the Oberheim OB-X8 - in both its keyboard and desktop incarnations - stands as a versatile and powerful tool for sound designers, producers, and performing musicians alike.
