I do a whole lot of tuba stuff actually - believe it or not and I usually use a real human tuba player. I have usually done about 8 jobs with him every year since 2008. This time I need the tube to not only sound awesome but also play slightly outside of human capabillities. I've used my tuba player for this kind of style before and through a whole lot of editing I have managed to make it sound the way I want.
This time I won't use him so I need to figure it out myself and this is the way.
So to me, this tuba patch is great! I'd buy this thing for $150 - but don't tell them that

And I will continue to use my tubaplayer when I can.
