Background and Identification
The OP-1 is a portable music workstation incorporating a synthesizer, sampler, sequencer, multitrack recorder, drum machine, mixer, and controller made by Teenage Engineering, a Swedish consumer electronics company founded in 2005. The OP-1 was released in 2011 as Teenage Engineering’s first product and is considered the company’s core product.
The OP-1 is known for its untraditional design, AMOLED display, and the depth of its eleven synthesis engines. The synthesizer combines multiple synthesizer engines, sampler, four sequencer types, a tape-style 4-track recorder, a motion sensor, and an FM radio. The OP-1 has received some criticism for its physical limitations, but Teenage Engineering has said these limitations encourage user creativity. Teenage Engineering introduced several accessories for the OP-1 in 2012 that can be used to manipulate the OP-1’s macro effect knobs. The price of the OP-1 increased by about 35% in 2019 to cover new parts and redesigned hardware.
The OP-1 features a 320 by 160-pixel OLED (organic light-emitting diode) screen, which displays a graphical representation of the synthesizer’s current mode. The device includes a fixed-velocity keyboard with 24 keys. Arrow keys can be used to move up or down entire octaves while in drum or synthesizer mode, and the device has a range of eight octaves total.
The OP-1 includes the model name “OP-1” in the lower right-hand corner of the device, printed vertically in capital letters.
