TEO-5 Desktop Analog Synthesizer

Drawing from the classic Oberheim SEM filter lineage that defined '70s and '80s synth tones, this desktop module packs five voices of pure analog punch into a compact footprint perfect for any rig.

Each voice rocks two voltage-controlled oscillators offering triangle, saw, variable pulse, and noise, plus a sub-oscillator, with hard sync, dedicated X-Mod for through-zero FM, and switchable key tracking. The state-variable SEM filter morphs seamlessly from low-pass through notch to high-pass via a single knob, with band-pass mode and bipolar envelope amount, paired to dual five-stage DADSR envelopes modeled after the OB-8. Poly and mono LFOs deliver five waveforms with tempo sync, feeding a deep modulation matrix of 19 slots, 19 sources, and 64 destinations, while enhanced unison stacks voices from 1 to 5. Hands-on front-panel controls include a vintage knob for authentic voice inconsistencies, arpeggiator, 64-step polyphonic sequencer, dedicated overdrive, reverb, and multi-FX like Oberheim phaser and ring mod emulations. Measuring 22 x 8 x 3 inches with stereo 1/4" outs, headphone jack, and CV/footswitch inputs, it stores 256 factory plus 256 user programs for instant recall.

Players love its immediate, expressive Oberheim growl that sits perfectly in mixes, though some note the five-voice limit shines brightest in leads and pads over huge chords.
