Thanks a lot, I'm glad you liked the music!
The Amiga's Paula chip, on its own (i.e. when fetching the data via DMA), can go up to more than 28 kHz when the screen mode is PAL or NTSC; however, on the ECS and AGA chipsets, when the screen mode is (for simplicity) a VGA-like one, Paula can go up to about 57 kHz. On all Amigas, however, Paula can also be fed by the CPU (which is exactly what this demo does), so the ceiling basically becomes the raw CPU power and memory and storage device throughput. My A1200, equipped with a 50 MHz 68030, 60 ns FAST RAM and a CF card, can easily play stuff at 200+ kHz (which is clearly silly).
