Woah!
Tack Kjetil!
I've been meaning to construct something like this for a veery long
time, I'm sincerely happy that you managed to pull it of!
Sometime in the near/distant/close/far future I'll be able to test this
(I'm not holding my breath), I can't wait!
So...next step would be VST synths, any chance you would pursue that? :)
Thanks again,
Robert
(now I can concentrate my -100% freetime on my other 101 projects ;-)
