Rebel Technology Witch, polyphonic digital Synthesizer with programmable DSP

Rebel Technology Witch, the programmable power of the Befaco Lich module packed into a compact multi-engine digital poly Synthesizer with MPE, and more.

With the Lich, Rebel Technology recently showed us an improved version of their Owl module. This was developed in collaboration with the Barcelona-based company Befaco. Like Owl, Lich is a programmable DSP that can be loaded with various algorithms. From whole synthesizers, effects, and more. A review will follow in the near future.

The highlight for me at the Lich is the new interface that makes handling much easier and clearer. With Witch, Rebel Technology is continuing their Owl Platform modernization process and infuses the power of the Lich module into a compact, standalone Synthesizer. And yes, it’s fully customizable.

Rebel Technology Witch

Witch is described as a compact and versatile Synthesizer with MPE support. Like the OWL and Lich modules, it is based on the same programmable DSP engine. Thus, you can load patches from the official OWL library (300 patches +) or creates your own.

It supports DSP languages (Pure Data, Max Gen, SOUL, Faust, Maximilian, and C++) which gives you a lot of creative freedom to craft your codes. Exciting for many, overwhelming for others because many do not associate coding with music-making. But Rebel Technology has thought of all non-coders and programming beginners.

They ship Witch hardware with four unique, ready-to-use DSP engines

  • SubTract Virtual Analogue synthesizer with 48dB resonant filter
  • VoSim Voice Simulator formant synthesizer
  • WaveBank Morphing wavetable synthesizer
  • QuadSampler Sampler with peak filter

MPE Support

The engines are anything but weak. Each of these synth engines has two modes: Expression Mode offers continuous pitch control and MPE support and Performance Mode with discrete pitch control, standalone chords, and classic MIDI support. Then, you get two assignable tap tempo LFOs with continuously variable shapes and a versatile effects section.

Further, there is a browser-based Synth Editor where you can edit With easily. Here you can load in your own or downloaded patches from the OWL library.

A look at the interface shows us that Witch is more than just a Synthesizer. It has two USB ports including a host functionality, stereo inputs, and outputs as well as CV connectivity. This allows you to turn Witch not only in a synth but also in a stereo sampler, effect processor, MIDI controller, sequencer, and more. And the red/black bananuts tell us that this is another collaboration with Befaco.

At first look, a powerful, cute digital Synthesizer. The possibility of exchanging the engine or even developing yourself is exciting. Who doesn’t dream of an own developed hardware Synthesizer? With your own code, part of the dream becomes a reality.

Rebel Technology Witch is available for 295€ in a fully assembled version or as a kit version from Befaco.
