I'm planning that has a backup, but I'm concerned that I will loose sync due to the differences between the sound CPU's clock rate (120.0 BPM for example), and the video display's clock rate (29.97 frames/sec for NTSC and 25.0? for PAL). The difference between these rates may be difficult to track using integer math. I'll probably have to add code to insert drop frames in my quess as to where the music is at any moment. Maybe I'm over estimating the difficulty with this, but I thought I'd check with Sony first to see if there was an easier way. I'm disappointed that they didn't respond to me even just to say "No"! > Are you a fan of Date Kyoto then? She rules. Yes I am! She's quite impressive. We don't get to see anything of her here except on the internet. It would be interesting to see one of her videos. David White
