The main panel is a faithful recreation of the Synthex’s original primary components, including its highly praised BBD chorus. But you also get a pair of selectable oscillators with various processing options, including “pulse width cross modulation”, where one oscillator modulates the pulse of the other. When this feature is engaged along with a hard synchronization, you get the Laser Harp effect, which is so visually captivating that it has been a main concert feature at every show by synth pioneer Jean-Michel Jarre since 1981.

There is also a multimode filter with 12 and 24-pole low and bandpass filters, a noise generator, a pair of dedicated envelope generators, basic modulation controls, a sequencer editing area, and more. And on top of all these classic features, XILS has included a host of additional features made possible by the digital era, such as assignable modulation envelopes, a dual-layer arpeggiator, 300 factory library presets, and 3 new vintage-sounding effects: phaser, delay and analog EQ.
