Thanks both.
They both work. I have no idea what I was doing incorrectly, but I'm sorted now.

Sorry to revive an old thread but I'm at a loss here.
I've created a track in Vortex Tracker II, compiled it as described above, assembled the loader exactly as described. Problem is I can't get the track to loop. It finished playback and just ends. I've tried it with a few different files, including a track I made myself. I've even tried two different versions of Vortex Tracker and I'm having no luck with either.

Do you have a loop position (L) in your position list?

Yes, it's currently i the middle of the track, but I have tried it at the beginning as well.

I figured it out. The previous code seems to be based on the VT tracker example code for play once and then stop.
This code makes the module play over and over until a key is pressed.
Code: Select all
ORG 49120
CALL #C000 ;calling init
EI ;enable interrupts
Loop HALT ;wait for next interrupt
CALL #C005 ;call play
XOR A ;test keyboard
IN A,(#FE)
CPL
AND 15
JR Z,Loop

Are you trying to play a vt2 or a pt3 file?
As for the pt3 player I use, it uses a so-called "setup" byte to indicate if the tune has to be looped or not.
