Well, what better to make my post about, than a short instrument test I did? Yes, this was only just a test to see if the organ worked! And before you ask, YES, this was made all with OpenMPT! ;D

Don't have to ask if you provide the module file. ;D - it's not mandatory of course, but it's always appreciated so that people can learn from each other, especially when it comes to music that is not "traditional" tracker music.
I don't have much to say about the song as I'm not that much into metal, however on a technial side I was a bit surprised that the organ in the intro is all mono. It sounds very sterile that way. Maybe a bit of reverb or chorus could have helped there, in particular since the organ later seems to be in stereo.
