JenDie

JenDie is an unofficial software emulation of the Jen SX-1000, a monophonic analog synthesizer produced in Italy during the late 1970s. The original hardware is celebrated for its warm, singing character, its four-pole transistor ladder filter capable of self-oscillation, and its straightforward layout that makes programming intuitive despite offering extensive sonic control. JenDie faithfully recreates the signal architecture of the original hardware with analog imperfection simulation.

VCO engine with PolyBLEP anti-aliasing (SAW, SQUARE, and PULSE waveforms).

Variable Pulse Width and LFO-controlled PWM.

MM5837-accurate 17-bit LFSR noise generator with white and pink modes.

Nonlinear Moog Ladder Filter based on the Huovilainen model capable of self-oscillation.

Dual independent exponential ADSR envelopes for VCF and VCA.

LFO with DAW tempo sync for modulating pitch, pulse width, and filter cutoff.

Glide (portamento) control with a 0 to 3 seconds range per octave.

Authentic mode enabling analog imperfection simulation (VCO thermal drift, waveform asymmetry, noise floor).

Fully automatable (27 parameters) and MIDI pitch bend support (±200 cents).
