It’s a sequencer. It’s a sampler. It’s a performance instrument. It’s the OP-XY from Teenage Engineering, and it’s a portable music powerhouse. Accessing the myriad tools on board is easy via the tactile controls, including a keyboard and pressure-sensitive pitchbend, with a monochrome display that uses red only for recording and status indicators. Once you’ve got a basic composition laid out, the Brain can transpose your chords and melodies to match the harmony, while punch-in FX give live playback a boost. Multiple inputs and outputs join USB-C in helping it interface with a slew of other gear, making this a versatile audio machine.
