In version 5.9.6. XM-modules are NOT playing right. To check:
Please listen to this attached xm-file with FastTracker 2.0.9 or MilkyTracker 0.90.85.
Then load the same xm in PlayerPro 5.9.6. press play. and listen to a [BUG} very out of tune version.
A nice xm that follows the MilkyTracker distribution.
