The Incredible Matrix Modular Analog Synthesizer. The XILS 3 V2.0 not only emulates the Synthi ( VCS 3 ) modular synthesizer, it also adds an emulation of the 256 Analog Sequencer, the natural companion of the VCS 3. Is that all ? No, of course, we added a SECOND Matrix, offering 2 additional envelopes, one LFO, a detailed Sample and Hold module, and a Voltage processor.
