OB-X8 - Desktop

DesktopAnalogPolyphonic

$3,499

For the first time in over 40 years, the legendary punch of Oberheim's OB-X sound is back in a compact desktop form, packing eight voices of pure analog polyphony into a sleek module that fits right on your desk.

Two discrete SEM/OB-X lineage VCOs per voice churn out saw, square/pulse, triangle, and noise waveforms with variable levels, cross-modulation, and hard sync for that classic thick tone. Authentic SEM filters handle low-pass with extra modes like high-pass, band-pass, and notch, plus genuine Curtis filters for OB-Xa/OB-8 bite, all feeding into dual envelopes and a versatile LFO with fresh destinations like independent osc levels. The front panel brims with 40+ hands-on knobs for instant tweaking, a high-res OLED display for patch management, and bi-timbral operation for splits or layers; stereo/mono outs, CV/gate inputs for clock/volume/filter/sustain, MIDI/USB, and an arpeggiator round it out in a 22" x 8" x 3" walnut-accented chassis with fanless power.

Players love how the Vintage knob nails that organic voice drift of the originals, while binaural panning and enhanced unison deliver massive stereo width—though some wish for a headphone jack, it's a beast for integrating into rigs where desktop size meets desktop-shaking power.
