JenDie is inspired by the legendary Jen SX-1000 — the classic Italian monophonic analog synthesizer of the late 1970s — reimagined for your iPhone and iPad. Every oscillator, filter, and envelope has been carefully modeled to recreate the warm, gritty, unmistakable character of that vintage analog sound, now in a modern, touch-first instrument. Use JenDie as a standalone synth or as an Audio Unit (AUv3) plug-in inside GarageBand, AUM, Cubasis, Logic Pro for iPad, and any AUv3-compatible host. KEY FEATURES • Faithful Jen SX-1000 emulation — true-to-hardware VCO, VCF, and envelope behavior, including analog drift for an authentic, living tone. • Authentic & Clean modes — choose vintage character or a cleaner, more precise sound. • Continuous waveform morphing — sweep smoothly between waveforms instead of switching in steps, with automatable control for evolving leads and basses. • Pulse width & PWM — shape and modulate the pulse waveform for rich, animated timbres. • 46 factory presets — from classic vintage leads and basses to new morphing patches designed for automation. • Full preset management — save, organize, and recall your own sounds; presets are stored in the Files app for easy backup and sharing. • Multi-touch keyboard — playable on-screen keyboard with multi-finger support. • Pinch-to-zoom interface — zoom and pan the panel for precise control on any screen size. • MIDI support — play JenDie from any connected MIDI controller, with a built-in MIDI Panic control. • Optimized for iOS — efficient DSP designed to run smoothly on iPhone and iPad. WHO IT'S FOR Whether you're a synth enthusiast chasing that vintage monophonic sound, a producer who needs a characterful lead and bass machine, or a sound designer exploring evolving textures, JenDie delivers genuine analog attitude in a portable package. Download JenDie and bring a piece of analog synth history to your mobile studio.
