OP-1 Field

The Beauty of Evolution — Meet the All-New OP–1 Field

The OP–1 Field is the natural next step in portable music production. Built on over a decade of innovation and feedback from professional musicians, producers, and sound designers, this is a complete reimagining of a modern classic—refined, updated, and elevated in every way.

Housed in a beautifully machined natural anodized aluminium chassis, the OP–1 Field features a slim, low-profile frame with a new floating keyboard and refined color palette. The high-resolution screen is protected by flush glass, and the entire signal path is now fully stereo - from input to output.

Packed with over 100 new features, it introduces stereo tape machines, multiple recording formats, eight tape reels, a new lush-sounding reverb, and the brand-new Dimension synth engine. The redesigned speaker system, now with a passive radiator, delivers detailed, rich, and surprisingly powerful sound.

Stay fully connected with upgraded USB-C, a rugged 4-pole audio jack for headset mic support, and durable line in/out sockets. Bluetooth MIDI, MFi support for iPhone, and a newly enhanced FM antenna (now capable of both receiving and transmitting) ensure total creative flexibility, wherever you are.

With 24-hour battery life, 32-bit audio, dual Velcro back fasteners, and intuitive graphics redesigned screen by screen, the OP–1 Field isn’t just an update—it’s a revolution in portable music-making.
