This desktop powerhouse captures the legendary OB-Xa vibe with authentic recreations of those mythic 3340 and 3320 chips, delivering the thick, characterful tones that defined '80s synth classics in a super compact package.
At its core, it's a 16-voice polyphonic analog beast with true multi-timbrality, letting you split or layer sounds across the keyboard range. Each voice rocks dual VCOs pumping out saw, triangle, or square waves with PWM and sync, feeding into dual VCFs—switchable 12/24dB low-pass slopes with resonance that bites just right. Two ADSR envelopes shape the filter and amp, while dual LFOs with seven waveforms modulate pitch, pulse width, or cutoff; an eight-channel mod matrix unlocks wild routing possibilities. Hands-on control comes via 26 knobby rotaries for real-time tweaks, an LCD display, and 512 preset slots with compare/match functions. The dual arpeggiator and sequencer even transpose in real-time, plus MPE support for expressive play. Connectivity shines with full DIN MIDI in/out/thru, USB MIDI, CV/gate/clock I/O, expression/footswitch pedals, balanced stereo outs, mono out, and headphones—all in a rack-mountable chassis measuring just 4.68 x 18.14 x 8.83 inches, complete with ears and a quiet rear fan.
Players digging its big-keyboard sibling love how this squeezes the same massive sound into tight studio spaces without skimping on the analog soul—though some wish for a USB host port. It's a studio staple for anyone chasing that Oberheim magic on a desk or in a rack.
