- First it is possible to make your 64 stereo by adding a second sound
- chip. You can either buy a cartridge, or make your own. I have plans
- for them floating around at home. But it would probably be easier to
- buy one. And I can't for the life of me remeber who sells them.

- Fast music? The music sounds fast, but otherwise it sounds ok? Sounds
- to me like you have a PAL player, on a NTSC machine. (yes there are
- more raster lines on PAL than on NTSC) The problem is PAL runs at
- 50hz.The screen is updated 50 times a second. If the music is called
- each time the screen is updated, it will take 50 calls to move the
- music up one second. In NTSC the screen is updated 60 times. Therefore
- the music is faster. Not only is the speed a problem(but not a
- terrible one) The note frequencies are also different. And although
- most European music players get 'fixed' for the timing problems. I
- have only seen one where the frequency was also fixed.
-
- BUT This really shouldn't be a problem with SID, unless your only
- playing tunes composed in europe....
