In Microstudio, harmless; in Hoster, not so much
I don't consider Microstudio to really be a Karaoke Player, just a "tester". If the "tic" is just what comes with Microstudio, and it doesn't appear on discs created by Microstudio and played in a real player, then that is pretty harmless.
If it appears on Hoster, then that would seem to be a problem.
My guess is that it is a hardware problem, but I don't know.
