Retro Synth vs Depmin

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. 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.

Depmin is a synthesizer app that pays homage to the theremin, using the TrueDepth sensor to play. It converts the distance to the nearest object into pitch and produces sound by touching the display. Volume and effects can be adjusted based on the touch coordinates. Please note that this app cannot be used on some devices that do not have Face ID.
