I don't know if this has been asked on here or not.  I mean, 121 pages is a lot to read.  If it's been asked already, feel free to direct me to the post that answers it. 
But anyway, I have Fruity Loops Vs. 5.1.  I'm a total n00b to it.  I can put piano rolls and beats in it, and it will play fine.  But when I import a Midi into it, no sound will play.  It automatically converts the tracks onto piano rolls.  And they seem like they should play fine.  I've done everything I think I'm supposed to do.  But it won't play.  Any suggestions?  Thx.
