Imagine a DJ mixer shrunk down to fit in your pocket, yet powerful enough to sync with modular synths and run full sets without a laptop in sight. After over a decade in development, this open-source gem bridges DJ workflows with DAWless production, letting you mix tracks, loop on the fly, and record multi-track sessions anywhere.

At 6.2 x 3.2 x 1.43 inches and just 8.2 oz, it slips into a bag with its rechargeable battery for hours of instant-on use. Load your library—MP3s, WAVs, AIFF, FLAC—onto 32GB internal storage or an external drive, then mix two decks with tempo-stretched playback, beat grids, keylock, hot cues, and a single jog wheel for nudges and scratches. Context-aware knobs handle 3-band EQ per channel (+12dB/-∞dB), gain staging, filters, and effects like delay, reverb, and flange; a crossfader and play/cue buttons keep it tactile. Dual stereo TRS ins/outs (splittable to 4x mono), dedicated headphone cue, USB-C audio/MIDI/hosting, clock I/O, and CV/gate make it a sync hub for external gear.

Hardware fans love its minimalist layout and hybrid potential, though some note the tiny controls take practice for booth-level precision.
