Yoy’re not kidding it sounded like a soprano sax Melodica-Me.
I caught this on youtube last night and for a little bit I thought someone might be having me on with a MIDI sax sample or some such. Then I saw your familiar profile pic flash on screen and I knew it must be you. That’s quite a performance. Did you record the hyper directly from it’s output? Is that part of that sax-like sound?
