louder, thinner and 100 times better. introducing the all new OP–1 field. injected with more than a decade of ideas, refinements and improvements. just to mention a few: stereo throughout the whole signal chain, bluetooth midi, usb type-c, a new speaker system with a passive driver for detailed, fat and loud sound, a massive 24 hour battery life, multiple tapes and recording formats, new great sounding reverb and the 'dimension' synth engine, an all glass, flush, high resolution display. we also meticulously reworked all graphics, screen by screen. did we mention fm broadcasting? well, that's just some of the 100 new features!
