Meet the PCM2612 Retro Decimator Unit, a bitcrusher effect plug-in for Windows, macOS, GNU/Linux, and iOS, with a distinctive legacy. Based on the work we made on the RYM2612 Iconic FM Synthesizer, our tribute emulation of the Sega Genesis sound chip, the 8-bit decimation is inherited from the FM synth’s PCM playback feature, packed in a simple and compact effect unit. Bonus: it’s free!
