The XILS 4 is a sophisticated analog matrix modular synthesizer inspired by the unreleased EMS VCS4 prototype, featuring two interconnected VCS 3 Synthi cores combined with a renowned 256-step analog poly-sequencer. This powerful design offers extensive modulation capabilities through a large pin matrix and a variety of modules such as envelopes, LFOs, sample and hold, voltage processors, and pitch tracking. Integrated effects including analog chorus, delay, phaser, and spring reverb enhance the sound palette, creating a rich and immersive analog synthesis experience.

With over 1,140 connection possibilities per patch, the XILS 4 allows complex signal routing at audio rate, making it an inspiring tool for deep exploration of modular synthesis. It features 12 aliasing-free oscillators in pairs with wave shaping and hard synchronization, multimode analog filters with non-linear behavior, multiple envelope generators, and polyphonic LFOs. Additional components like a polyphonic ring modulator, cascade mode for linking synthesizer engines, independent stereo outputs with filtering, vector controllers, and a versatile polyphonic sequencer expand creative options. The synthesizer supports multiple play modes, polyphonic aftertouch, and advanced portamento features, offering expressive performance controls.

Designed to push boundaries, the XILS 4 delivers nearly 700 presets crafted by renowned sound designers, along with a comprehensive preset database and an intuitive manual with tutorials to jumpstart your workflow. Over 100 parameters are MIDI-mappable, allowing deep integration with external controllers. For those new to modular complexity, the synthesizer includes a preset factory library with over 350 specially designed sounds plus the XILS 3 library, making it accessible while maintaining vast programming potential. The XILS 4 transforms previously impossible synthesis ideas into reality with limitless creative possibilities.
