I don't recall this ever happening in the past, but the past day I've been experiencing tone problems. The tone is the usual distorted one when the game starts, but once I start up a song... it goes clean. I have tones saved on my keyboard, and even when changing those it's still clean. The only way to fix it is to restart the game, and when I do the tone might stay for a song or two; that's it though. Is there a fix for this? Would CDLC be an issue?
