Quoted from gweempose:I noticed a strange sound thing as well with my TZ. During attract mode, the game played it's usual music, and then the last note sort of hung there forever. I don't recall that ever happening prior to installing the daughterboard. I turned off all attract mode sounds, so hopefully it won't be an issue going forward. I haven't noticed any anomalies yet while actually playing the game.
FWIW, I don't have Rob's board in my TZ (Great product btw Rob!) but I had that same thing happen once. I had hit the flipper button while that attract music was going and the horn honked (flipper button) and held the one long note from the attract song. Maybe a bug? I started a game and it went away but stayed with that high pitched tone for 30 seconds. Who knows how long it would've gone for.
