OP-S is a complete smartphone synthesizer that fits in your pocket inspired by the simplified design language of TeenageEngineering OP1 & OPZ. This concept lets musicians take their music production system with them everywhere. A full keyboard, audio I/O with 32bit DAC, built-in 4 high-capacity surrounding microphones, front-facing speakers, immersive screen and a set of three cameras make up the perfect tool to create as well as share the creative process on the go.
