Description

Radioactive is a 14-bit analog modelling voltage-controlled digital sound source. In short – a complete Eurorack voice in just 6HP.

Packed inside the Radioactive voice there are 3 x simultaneous independent oscillators, a voltage-controlled AR/ASR transient generator, a voltage-controlled pitch slew (glide) and a voltage-controlled waveshaper with 5 different modes, and more! Other features include selectable gate/trigger/constant envelope timing signals, a rather unique 3-voice polyphonic mode, semitone quantised mode, voltage controlled waveform selection and a few experimental features for good measure!

At its core this module is a highly experimental chiptune inspired wavetable-ridden Lo-Fi sound generator that’s pulling an absolute maximum out of its simple 8-bit MCU. It will sometimes roar, glitch, pop and buzz like crazy and alias on very high notes when some odd waveforms are selected, and
you can’t do anything about it except love it or turn some pots down and hope it will behave. It just isn’t a nice VCO and it was never meant to be one – Radioactive was purposely made it to be wild, raw and untamed. The world is full of nice VCOs.

Radioactive – User Manual

Operation

  • V/Oct Pitch input with attenuator

  • 3 CV inputs with offset (Glide/Attack, Release, Shaper)

  • Trig/Gate input for envelope triggering/gating

  • Wave change trigger input

  • Single button with 3 different functions: waveform change with short press, shift function (alternate control parameter) with long press, enter setup mode on power-up.

  • 3 green illuminated indicators of selected waveform and their combinations, also providing information in setup mode

  • Single red illuminated indicator of incoming trigger or high/low gate signal

  • Simple and intuitive setup without menu diving (parameters are saved and recalled at start-up)

  • 3 different operation modes (A, B & C) selectable in setup:

A – Free range oscillator with Attack and Release envelope

B – Free range oscillator with Release envelope and Glide

C – Quantized oscillator with Release envelope and Glide

  • 3 different envelope activation modes (G, T & P) selectable in setup:

G – Gate mode, monophonic

T – Trigger mode, monophonic

P – Poly mode, 3-voice polyphonic

  • 5 different wave shaper modes selectable in setup and at runtime

  • 9 basic waveforms and 12 different combinations
