i'm getting close. i really am.
i decided there was a headphone issue, and i should just go ahead and deal with the clock - started fading as soon as i opened cubase, as expected. so, i reinstalled the clock. and - bam - it's sounding perfect again.
i'll have to see what happens when i open cubase. i still need to do some more testing first.
in the meantime, i'm going to repost this instrumental remix of confused, with the added sequencer, because it's a new mix, and i'm really jonesing to move forward.
