Sega Megadrive sound chip based generative drum machine
OPERA ROTAS is a mutant, generative drum machine. It's built around a Yamaha OPL2 FM audio chip, a close cousin of the one used in the Sega Genesis / Megadrive consoles.
At the core, it has a real Yamaha OPL2 audio chip and live sounds bonkers, brutal. It's all body and weight while being crystal clear and punchy.
