Some additional information: With the next release, there is going to be a new mix mode, which is designed to be more compatible with other trackers. It's basically the same as mix mode RC3, but with soft panning disabled (this is forced, as it creates a completely different stereo spectrum) and slightly lower mix levels. This will be the default mix mode for MOD/S3M/XM/IT (you can't choose the mix mode for MOD and S3M, actually).
