Retro Synth vs PocketStrum

Play a real pocket stylophone — then plug it straight into GarageBand. Retro Synth · Syntophone turns your device into a vintage touch-keyboard synthesizer, and now works as an AUv3 instrument inside GarageBand, Logic Pro, and AUM. Slide your finger across the keys and a warm, authentic square-wave synth comes to life. Learn built-in songs with light-up "follow the key" tutorials, record your ideas, and drop the instrument into your favorite music app — all from one tiny synth. Like the original, it plays one note at a time: one stylus, one note. Curious about Pro? Tap any locked sound and hear it free for 30 seconds. FREE FEATURES (Included at no cost): • Authentic Vintage Sound: faithfully recreates that iconic square-wave tone with modern precision. • Song Mode: learn songs with light-up "follow the key" tutorials, hold-to-repeat for repeated notes, and a star rating when you finish (2 songs free). • My Recordings: a full library to play back, rename, share, and delete your takes. • Metronome: a sample-accurate click with adjustable BPM and an accented downbeat to keep you in time. • AUv3 Instrument: use Syntophone as a plug-in inside GarageBand, Logic Pro, AUM and other AUv3 hosts. • Sound Controls: shape your tone from thin and bright to thick and warm, and add expression with vibrato. • Real-time Response: instant, zero-latency audio as you play. • Clean, minimalist design inspired by vintage hardware.
