I am extremely inexperienced with the use of synthesizers as a form of writing music and therefore have been having a few issues. This one that I'm about to mention is regarding Reason 4, of course. The largest issue I'm having at the moment is that whenever I try to add a low drum (Big Fat Drum for Example), whenever the drum plays, I get a lot of noise/scratchy-ness out of my composition. If I play the drum solo, it sounds fine. If I play everything else solo, that sounds fine as well. It's only when the bass and treble play together. Any suggestions?
