Epicjambox
Neon synthwave jam machine
$4.99 · Designed for iPad. Not verified for macOS.
Step into a synthwave cyber lounge. Generate a chord progression, build your sound with layered voices, drums, bass + FX, flip on EPIC mode, and jam.
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

• 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
