XILS Lab’s XILS 505 is an accurate emulation of the Roland RS-505 string machine that goes beyond what the original can do.

In Grenoble are not only the headquarters of Arturia but also the home of the Xavier Oudin better known as XILS-Lab. He’s back with a new classic emulation for 2020. XILS 505 is a digital reproduction aka emulation of the Roland RS-505. In addition to the same controls, many hidden parameters of the original have been made accessible and expanded with new ones.

One of the new features is a vintage analog-style human choir machine as an alternative oscillator source for the synth section. The XILS 505 is not just a string machine but also a Synthesizer and bass synth. It offers 49 notes of polyphony including layering, source mixing and more. If you search a Roland RS-505 sounds, here you will get probably the closest in software form.
