Behringer Proton is a semi-modular analog synthesizer that expands on the Neutron design with dual oscillators, multi-mode filters, and an extensive 64-point patchbay. Its rich analog tone, flexible routing, and built-in overdrive make it a powerful tool for bass, leads, drones, and experimental sound design.
