Thanks for the long and detailed response!
Actually, in my case I had what I thought was case A, no raster/border stuff.
Turns out that I was quite close to the limit on CPU time though. :/
Now I've got a new 50Hz tune from the musician, but I ran into problems again.
The SNDH-player takes up almsot 50 lines of raster time, which still is way too much!
I can't understand how the SNDH-player can take that much CPU-time on an 8MHz 68000.
Since the tune seems to be made in Vortex Tracker II (at least in the header it says so) that can make music for all AY/YM-based systems it can't be using any Atari specific timer effects etc. so I don't understand how the player can use that much CPU time to find out what to write in those 14 registers...
To save some time, I thought I would go with a straight YM-register dump instead, so I made a .PRG that played the music and then used Hatari to record it.
Now, the strange thing is that it seems like the playback of that does not sound *exactly* the same as the original player, and I don't know why. :/
