Radioactive is a 6HP Eurorack module that brings real-world FM radio into your modular system. Covering the 88–108 MHz range, it lets you patch in up to 6 actual FM stations, creating unpredictable textures, sampled content, or ambient backdrops. CV IN — Station Select (0–5V)

Selects one of six FM stations using control voltage. 0V = Station 1, 5V = Station 6. Intermediate voltages choose the stations in between. Ideal for sequencers, LFOs, or random CV. TRIG — External Random Select

A rising trigger performs the same action as the front-panel Random button, choosing a random active station. GATE — Output MuteGate

LOW: Output unmuted

HIGH: Output muted Useful for rhythmic gating or performance control. ANT — Antenna Input. Connect an FM antenna here for best reception or just use a Eurorack Patch Cable. OUTPUT — Stereo Audio Out. Main stereo output at Eurorack levels, carrying the selected FM station’s audio. QUANT — Quantized CV Out

Outputs pitch-quantized CV from the internal chromatic quantizer. Behavior depends on the current mode set by the Shift button. Buttons-  

Random - Immediately switches to a randomly chosen active station. Great for unpredictable or generative patches. Shift - Toggles between FM Mode and Quantizer Mode. FM Mode: Normal radio operation with CV station control. Quantizer Mode: Activates the chromatic quantizer and routes its output to the QUANT jack.
