Hello! I'm a video game programmer and I've never been developing any "music" program, and i just want to ask a few simple questions.
Is it possible to add an "Instrument plugin" (BitInvader, Kicker, Organic, etc...) like one of the VST of FLStudio called "Fl Keys" http://www.music-software-reviews.com/image-files/fruity-loops-fl-keys.jpg?
Its just a simple piano very handy.
If yes, is there any simple tutorial of the source code?

And also, my brother is a designer and hes working on a brand new theme and logo to make it look more "professional" ;)

Keep it up!! you are doing an awesome job!!
