PO-28 Pocket Operator Robot Synthesizer

MicroDigitalMonophonic

$99

Did you know this little powerhouse cranks out authentic 8-bit synth tones that nail that classic video game vibe, all from a device smaller than your phone?

At its core, it's a real 8-bit digital synthesizer with 15 preset sounds plus a micro drum machine for beats, powered by a 16-step, 2-channel sequencer that handles melodies on one track and drums on the other. You've got 16 punch-in effects like bit crush, stutter, delay, filters, and glitch for real-time tweaks, plus glide control for smooth portamento slides between notes. Controls are dead simple with 16 velocity-sensitive pads for playing, sequencing, and effects, two knobs for parameters like pitch, release, and swing, plus buttons for pattern chaining up to 128 steps, BPM presets (hip-hop at 80, disco 120, techno 140, or fine-tune 60-240), and parameter locks to evolve sounds per step. It's ultra-portable at 5" x 3" x 0.5", runs on two AAA batteries with a built-in Knowles speaker, folding stand for desk play, LCD display, mono audio in/out jacks, and Jam Sync to link with other Pocket Operators.

Users love its hands-on live performance flow and endless tweakability for chiptune jams or backing tracks, though some note the internal speaker is quiet and best paired with headphones or an amp for louder gigs.
