teenage engineering OP-1 Field Portable Synthesizer Workstation

$ 1,999.00

Professional musicians, recording artists, and sound designers in search of a highly portable music making device will be thrilled with the teenage engineering OP-1 Field, the latest flagship instrument that builds upon the success of the original OP-1 with over 100 enhancements, refinements, and upgrades. The aluminum body has been lowered around the keyboard and feels thinner, lighter, and more precise. There's also a 2.4 GHz antenna system that's been fitted inside, and the rear panel now has a plastic cover with two soft Velcro rings for fastening to covers and other accessories.

The OP-1 Field is now stereo throughout its entire signal chain and includes Bluetooth MIDI, USB-C, and an updated speaker system with a passive driver for detailed, fat, and loud sound. The battery has been expanded to 24-hours of continuous use, while the system engine offers multiple tapes and recording formats including Studio 4-Track, Vintage 4-Track, Porta, and Disc Mini. You'll love the new reverb effect and the Dimension synth engine. A flush, all-glass, high-resolution display is easier to read with all new graphics. The unit can also broadcast over FM for even more flexibility.
