    "I was struck by the originality of Pauline's approach and the promises that it can represent for all the saxophone players. Indeed, we are used to play with what the market is offering us and the offer is not only limited but has defects. Today, thanks to Pauline's research, it seems that the offer is as huge as the tastes of all saxophone players, she is not constrained by the manufacturing process and most importantly, Pauline does not simply display a wide range of mouthpieces but she accompanies the research, tries to understand very closely the musician's requests in order to make a custom mouthpiece, which is the dream of every saxophone player.

    "The mouthpieces invented by Pauline and 3D printed are a wonderful evolution: extremely flexible, adjustable, adaptable and reproductible at will.

    This offers saxophone players a way to look for new sounds, news perspectives and to look at the future!"

    Benjamin Dousteyssier

    "I found with SYOS a mouthpiece that I had been searching for a long time. Thanks to Pauline's expertise and imagination, I now have a tool with unique and personalized acoustical characteristics, with great flexibility and consistent with my equipment. SYOS process, completely new as it appears, has a lot of advantages, especially to provide each musician with a custom-made mouthpiece, reproductible and original. Moreover Pauline knows how to translate the sound wishes into parameters of the mouthpiece geometry, so that the result is often really close to the musician's initial idea."

    Pierre-Antoine Badaroux

    "Too often, the musician instruments makers and the musicians belong to distant worlds, which turns opaque for one, the practice of the other. Working with Pauline in implementing the production of an "ideal" sound is an very enriching, fun and inspiring experience. What offers SYOS, except for the wonderful opportunity of a custom-made mouthpiece, is a fascinating process of exchange, definition, experiment, adjustment, which accompanies the building of the mouthpiece and turns it into a very privileged moment for every musician."
