## What is Retro Synth?

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.

SYNTOPHONE PRO (subscription):
Upgrade to unlock the full studio:
• Premium Waveforms: Sine, Sawtooth, and Triangle.
• Studio Effects: high-quality Reverb and Delay.
• Pro Sound Panel: a second detuned oscillator for a fatter analog tone, hands-on delay time & feedback controls, and live MIDI output — play GarageBand and other synth apps as a virtual MIDI keyboard.
• 12 more built-in songs to learn.
• MIDI Export: save and share your recordings as .mid files.

WHY SYNTOPHONE?
No setup, no menus to fight — open the app and make music immediately. Then, when you're ready, it becomes a plug-in in your studio.
