Hi, seems like you discovered a bug in the code. I have not seen this problem, but I wouldn’t be surprised if I missed something ;)
So it can only play one pattern (one display) no matter where you are in the song, or is it only the last pattern of the song?
The function patternInc() at line 688 handles the next pattern and is loaded when curPos = 15 in the current pattern.
As you mention, it could be some error with the files, did you try the two songs I included on github?
