Delta Cep A 2

DesktopHybridParaphonic

Imagine a swarm of digital oscillators that can clone themselves up to eight times, detuning into thick, pulsating textures—this is the heart of what makes this hybrid synth stand out in Radikal Technologies' lineup of innovative semi-modular designs.

The desktop version measures a sturdy 352 x 135 x 97mm, packed with 23 knobs, 14 buttons, 28 RGB LEDs, 14 outputs, and 17 inputs for endless patching possibilities, whether standalone or integrated into Eurorack. Its single swarm oscillator handles waveform crossfading, TLM modulation, FM, and quantization, feeding into a mixing stage with noise, then a powerful filter section featuring an analog multimode filter alongside digital 12dB multimode and 24dB ladder emulations. Modulation comes from a versatile LFO with four waveforms and random voltage, plus a snappy ADSR envelope with voltage control over attack and decay; a VCA offers envelope or gate control, all enhanced by the snapshot interpolator for seamless morphing between saved states. The FX section delivers stereo magic with improved reverb, tape/tempo delay, chorus, flanger, phaser, and more, controlled via an interactive step sequencer and full MIDI implementation that sends knob automation to your DAW—plus 40 memory slots, a headphone out, and 6.3mm audio jacks on the rear.

Players love its vibrant, punchy paraphonic sound and creative depth without needing a full modular rig, though some note the single-oscillator core keeps things focused rather than overwhelmingly complex. As B-stock, this one's been gently used but fully inspected and ready to inspire.
