NAMM 2018 News: Radikal Technologies presents the Delta Cep A – a semimodular paraphonic synthesizer voice

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.

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