In less than two weeks, this year’s NAMM show will start in Anaheim. Already before the show Radikal Technologies has very exciting news to announce. The Delta Cep A is a new semi-modular paraphonic Synthesizer voice that can be used in the Eurorack world but also as desktop Synthesizer.

It features a fat sounding digital swarm oscillator, one analog & one digital multi-mode filter, a LFO, an envelope generator, a mixer, a VCA as well a FX processor section. One the big features of the new Delta Cep A is a memory/interpolator that can create very interesting sound FXs. Stay tuned for a first look and sound demo from NAMM 2018 next week.

The Delta Cep A is the perfect starting point into the Eurorack modular world. A MIDI to CV Interface, Oscillators, Filters, LFO, Envelope Generator, Mixer, VCA and a FX section and even a memory sequencer/interpolator for new incredible sound FXs. Each section has inputs and outputs and adds a lot of power to any already existing modular synth. The Delta CEP A can also be used totally independent from any Eurorack frame with our Delta CEP A desktop casing. Even without patching one single cable, the Delta can be used as a powerful solo Synthesizer and Chords/Pads machine.

Feature Overview

Interpolator: The Interpolator stores patch memories of the synthesizer and allows for automatic sequential recall and crossfading between these patches.

  • Controls: Interpolator/Patch Select knob
  • Buttons: Manual Mode/Shift, Tempo, Snap, Mute, Blend, Memory

Swarm Oscillator: The swarm oscillator is a bank of up to 8 oscillators that can be tuned in chords, clusters or fat detuned multi-oscillator sounds.

  • Controls: Wave/LTM knob), Pitch knob, Detune knob, Mod depth/Mod wheel depth/ Swarm density
  • Buttons: Paraphonic switch button
  • Control Voltage Inputs: FM, TLM and Waveform Modulation, 1V/Oct Pitch Input
  • Outputs: Swarm Oscillator Output

Mixer: The mixer controls the balance between external signals, the swarm oscillator and the noise generator.

  • Controls: External/Noise Level, Oscillator Level
  • Control Voltage Inputs: External Input, Modulation Input
  • OutputsNoise, Mix Output

Analog Multimode Filter & Digital Multimode Filter: The Delta has one analog and one digital multimode filter to choose from.

  • Controls: Cutoff, Resonance, Cutoff Mod/KB-scale, EG-depth/Velocity
  • Buttons: LP, BP, and HP switches
  • Control Voltage Inputs: Cutoff, Resonance, Filtertype-Interpolation
  • Outputs: Filter Output 

ADSR Generator: The ADSR Generator creates fast, snappy envelopes and offers CV control over Attack and Decay times.

  • Controls: Attack, Decay, Sustain, Release
  • Buttons: Gate
  • Trigger Input 
  • Control Voltage Inputs: Attack, Decay
  • Outputs: Envelope Out


  • Controls: Depth, Speed
  • Buttons: Waveform Select
  • Control Voltage Inputs: Speed, Depth, Sync
  • Output: LFO Out


  • Controls: Level, EG-Depth/Velocity
  • Button: EG/Gate
  • Controle Voltage Inputs: Modulation, FX In Left, FX In Right
  • Outputs: Dry Out

FX Section: The FX section is the perfect addition to this Synthesizer voice.

  • Controls: Time/Modulation Rate, Feedback/Modulation Depth, Dry: Wet/FX-Select
  • Outputs: Out L, Out R

MIDI2CV: The MIDI to CV Interface controls the internal Synthesizer and external synth modules.

  • Buttons: MIDI Learn Button
  • Inputs: MIDI
  • Outputs: Gate, KB-CV, CV, Clock, Clock Reset
  • 200 mA +12V
  • 50 mA -12V
  • 0 mA 5V
  • 23 mm deep

Availability & Price: TBA
