EPICJAMBOX — a synth-wave cyber lounge in Tron-land. Tap GENERATE and a fresh chord progression appears. Build a sound around it — layer two voices, dial in drums, bass and feels, sculpt it with reverb, delay and filter — then flip on EPIC mode for a full hyperspace light show, and jam. It's a harmonic jam machine built for flow: every tap gives you something new but musical, and it all runs instantly on your device. No sign-up. No internet. No data collected. Just you and the neon. WHAT'S INSIDE • Instant chord progressions across 7 styles — Psych, Rock, R&B/Soul, Pop, Lo-Fi, Jazz and Electronic • Layer two voicings at once — stack a lead and a wash (pianos, rhodes, pads, strings, organs, synths) • 8 drum kits • 6 bass voices • 20+ feels, from ballad and funk to techno, trance, DnB and dubstep • A full mixer — master, two voices, bass and a tone dial • FX — reverb, delay and a sweepable filter • EPIC mode — a beat-synced hyperspace light show and reactive visualizer • Build your own — write custom chord progressions with full root / quality / length control and song sections • Save your songs EPICJAMBOX vs EPICNOME Want a straightforward 12-bar blues or a clean backing track to practice over?
