@Laurent_AODYO Great. Thank you. I read on your main website about your collaboration with Pedro Eustache. Wow! I used to listen over and over his Youtube video playing the Armenian duduk. Such a haunting instrument! And I love that you all are so open to having more of the traditional instrument fingers and sounds on the Sylphyo. By the way, if you want to skype, I can show you the fingering of the 8 hole bamboo xiao in person. You can email me.
