junoNATIVE vs SJ

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.

SJ-SQUARE is a Super Jupiter–inspired analog polyphonic synthesizer for iPhone. A warm brown chassis and amber glow meet a hands-on module layout: oscillators, filter, envelopes, LFO, and effects — built for playing, not menus. FEATURES • Multi-oscillator panel with wave, octave, and level controls • Filter with resonance, envelope intensity, and key tracking • Filter envelope & amp controls for expressive shaping • LFO, OSC 2 detune / live layer, chorus, delay, and reverb • Unison (1–4 voices), tempo / tap, and scale snap • Full on-screen keyboard with octave shift & range minimap • MIDI input support for external controllers • Built-in presets ready to play • Landscape-optimized performance UI Craft rich pads, biting leads, and stacked unison tones. Tweak cutoff and envelopes in real time, then perform with the keyboard or your MIDI gear.
