Well, let me put this here even though it doesn't fit that perfectly...
On the old WB 1.3 Extras disk, there is a demo program in BasicDemos called 'Music', accompanied by nice graphics generated by means of math calculations.
For long, this demo didn't run well on WinUAE, probably because of the tight sync requirement of the buggy AmigaBASIC music "engine". Even '100% sound emulation' setting did never help much in WinUAE 0.8.8 R8.
But now, this is working very well!
It features a classical tune
from a well-known composer, but for the sake of it, I can't remember the name.
Can anyone help?
