What a beautiful instrument; everyone has their taste, but I do think these instruments sound as incredible as they look. I have one Roya concept and its sound spectrum is quite unique. The bass can produce a thick mid-tone and a crystal overtone at the same time which I have very rarely heard in other instruments. It cuts through stone when needed. Below an example (Interstellar), video quality is not the best, but I believe the sound is pretty good. Also at the end, some Miles Davis channeling using this beast’s MIDI capabilities. Hope you like it! Jens all the way…..
