About

Ring Modulator

This app creates unique metallic and bell-like timbres by multiplying two audio signals. It offers three modes for versatile sound design, from internal oscillators to sidechaining external audio.

Highlights
  • Ring modulation effect
  • Dual input capability
  • Three distinct modes (OSC+OSC, INPUT+OSC, INPUT+SIDECHAIN)
  • Mono and stereo input support
  • Adjustable carrier and modulator frequencies
  • Mix and output gain controls
Features
Read full description

Ring modulation multiplies two signals together sample by sample. The result contains the sum and difference of their frequencies, the sidebands, while the original carrier and modulator tones are suppressed. This produces the metallic, bell-like, and clangorous inharmonic timbres associated with classic ring modulators, from robot voices to detuned percussion. Signal path: the carrier is multiplied by the modulator to form the wet signal, Mix blends that against the dry carrier, and Output applies a final makeup gain. Ring Modulator is usable in three modes and can take either mono or stereo inputs. The host app must support mixing to bus inputs or sidechaining in order to use Ring Modulator with dual input. Outputs mono signal. OSC + OSC Both carrier and modulator are internal sine oscillators, set by Car Freq and Mod Freq. Produces classic two-tone ring modulation with no input required, good for bell tones and metallic drones. INPUT + OSC The carrier is your track's audio and the modulator is the internal sine at Mod Freq. This is the standard ring-mod effect: it turns voices and instruments metallic or robotic and adds inharmonic sidebands. This is the default mode. INPUT + SIDECHAIN The carrier is the main input and the modulator is a second, independent input routed into the plugin's sidechain bus. Use it to ring-modulate one track by another, for example a vocal shaped by a drum loop or synth pad. This requires a host that supports sidechain routing; if nothing is routed to the sidechain, the input passes through dry. Car Freq and Mod Freq do not apply in this mode.

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.
