junoNATIVE

junoNATIVE is a music synthesizer app. All audio is generated in real-time on-device. Tap the piano keys to play notes, use the control knobs to shape the sound.

junoNATIVE puts a warm, expressive polyphonic synthesizer in your hands — no hardware required.

Designed from the ground up for iOS, junoNATIVE faithfully recreates the soul of classic analog synthesis with a real-time audio engine built on AVAudioEngine. Shape rich, evolving sounds using authentic DCO waveforms, resonant filters, multi-stage envelopes, and a lush built-in chorus — all controlled through a beautifully crafted skeuomorphic interface that feels like touching real hardware.

SOUND ENGINE • 6-voice polyphony with per-voice oscillators, filters, and envelopes • DCO with saw, square, and sub-oscillator waveforms plus PWM modulation • Resonant low-pass VCF with cutoff, resonance, envelope mod, LFO mod, and key follow • High-pass filter for thinning out low end • ADSR envelope with snappy response for both filter and amplitude • Syncable LFO with rate control for vibrato, filter sweeps, and modulation • Three-mode chorus: Chorus I, Chorus II, and I+II combined for rich stereo width • Delay and reverb effects with adjustable mix, time, and feedback • Portamento for smooth pitch glides between notes

ANALOG CHARACTER Dial in the imperfections that make analog synths feel alive: • DCO Beating — subtle detuning between voices • Filter Drift — slow random cutoff movement • Envelope Click — percussive transient at note onset • Cable Length, Temperature, and Age controls for vintage warmth

ARPEGGIATOR • Up, Down, Up/Down, and Random patterns • Adjustable tempo from slow ambient pulses to rapid sequences • Hold mode to sustain arpeggios hands-free • Chord mode for instant polyphonic voicings

PRESET LIBRARY Browse a curated collection of patches organized by category — pads, basses, leads, keys, FX, and more. Includes presets inspired by legendary electronic music productions. Tap to load and start playing instantly.

INTERFACE • Skeuomorphic design with realistic 3D knobs, illuminated LED buttons, and wood-grain panels • Real-time oscilloscope waveform visualizer • Scrollable, zoomable piano keyboard with velocity-sensitive touch • Floating parameter overlay shows values as you tweak • Haptic feedback on every interaction • Optimized for iPhone

Built with SwiftUI and AVAudioEngine. No sample libraries. No MIDI required. Just pure synthesis.
