At the moment, I've just been copying source material note-for-note (which, I'm aware, isn't all that impressive, and wouldn't be worth judging because of that. >__>'), but I have to wonder, what is it, exactly, that I should be doing for a song to sound 'good'? I've downloaded a few soundfonts (virtually of which were free and made available by different posters here), and I've been using only those at the moment to reconstruct the source material.
My question is, I guess, is there anything more I could, or should be doing at this point to improve upon it? Should I wait until I've 're-made' the source material to do such? Should I even be re-making the source-material in the first place?
Any help here would be appreciated.
