Retro Synth - Syntophone
AUv3 Instrument: Learn Songs
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
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.
