The Teenage Engineering OP-1 Field takes the original OP-1 design to the next level, building on over a decade of research and development to create the ultimate portable synthesizer. Refined, upgraded and enhanced; nearly every facet of the original design has been overhauled including Bluetooth MIDI connectivity, a huge 24-hour battery life, new synth engines and a whole host more! From the studio to the stage, the OP-1 Field shines, featuring powerful onboard speakers with a passive radiator and a high-resolution flush display for navigating settings and parameters. You can even sample from the radio using the onboard FM antenna. Not only that, but the OP-1 Field now allows you to broadcast over FM too! The new and improved stereo sample engine takes your sampling capabilities to the next level, with an increased sampling time of up to 20 seconds. The overall sound quality has also been improved with 32-bit audio fidelity. Seven new stereo synth engines allow you to explore a wide range of synthesis styles and options including refined envelopes, 20 new preset patches and expanded audio connectivity. You can now store up to 160 minutes of samples and up to 500 user patches; making it perfect for musicians on the move. The overall design has been upgraded too, with a thinner, low-profile aluminum body and new graphics/colour scheme. You can even wirelessly connect (via wireless MIDI) to other Teenage Engineering gear such as the OP-Z and the TX-6 mixer.
