Summary0001745: Possible glitch in

I noticed that in the above module,, starting at around 3:40, some of the lower notes sound filtered in other players such as XMPlay, but it sounds like they might not be getting filtered when played in OpenMPT.

It seems like this module has the strange / unusual combination of declaring to be saved with IT 2.15 but using an IT format subset compatible with IT 2.00. I have never seen IT 2.15 writing this combination. Unfortunately OpenMPT checks for the "compatible with" version number rather than the "made with" version number when deciding whether to clear Zxx MIDI macros (filters were introduced in IT 2.14, so a file saved with IT 2.13 containing Zxx commands should not enable any filtering), so in this particular case OpenMPT decides to clear all MIDI macros because the file is compatible with IT 2.00, but it shouldn't do so because the file was made with IT 2.15.
