I never got around to building one; but I also don't do much
   music producing smile emoticon It's on my "someday list"... put
   together a decent library... get the tools... learn to use
   them... get some patience ... get organized... yeah.. I can't
   see that happening for me tongue emoticon So, I do things in a
   "grab as I go" fashion when i make Vines.. which is really the
   only reason I typically collect samples and loops. Still haven't
   found "the music editor" I want. It's silly of me really, always
   seeking shortcuts when there's none, but I keep hoping
   _somebody_ will write something that breaks from tradition.
