Summary0000385: panning error in "Sick on Monday" by Elwood (XM module)

In the XM module "Sick on Monday" by Elwood, OpenMPT's panning in pattern 20, channels 22-24 does not match FastTracker 2. Channel 22 should be panned center, 23 panned right, and 24 panned left. OpenMPT plays all three channels panned center. Linked below is a .zip file containing comparison audio between FastTracker 2 and OpenMPT as well as the original XM module file. XMPlay's playback matches that of FastTracker 2. Disabling the FastTracker 2 compatible playback mode in OpenMPT doesn't solve the problem.

Steps To Reproduce
  1. Download the zip file containing the XM module and test audio files:

  2. Open the XM module from the downloaded archive.

  3. Solo tracks 22, 23 and 24.

  4. Play pattern 20.

Yeah, I know about that one, but I haven't been able to find a fix for the last two years...

Seems like it was rather easy to fix by viewing the problem from a different angle. Please test:

I can confirm that the panning is now correct.
