Its still impossible, unfortunetly... Well, unless you wanted to spend months or years editting every single shape that has the bongos in them.
Sounds are made up of vibrations, right? Depending on how close or far together these vibrations are makes the sound everything makes. Its how different pitches on instruments are made; For example, on a guitar, depending on how long or short the string is is how deep or high pitched a note is.
Computers don't hear sound, they read it. Sound, in a computer, basically looks like a whole bunch of squiggly lines, or shapes. Shapes make up a sound when veiwed through an Oscilloscope(Like the one in FL). Basically, all the instruments, including the bongos, are on 1 single wave form. Because of this, as far as I'm aware, computers can't remove any sound and leave just 1 specific sound playing without extreme quality loss.
I apologize if thats hard to follow... Sounds are a hard thing to explain.
So it's impossible... If it isn't, some one please correct me if I'm wrong.
