Hi Waccoon,
I think you'll agree with me that it's impossible to please everyone. For instance, Windows MP9 is awful for you; for me it works like a charm.
I know that some people will simply hate ProTrackerII and others will love it. The concept of a Tracker is based on loading a collection of samples/instruments and writing the music as a list of positions each containing a note, effect and parameter. The song is a sequence of patterns, a pattern is divided in tracks.
Of course, there are other paradigms for music composing, and they have their place. But this is ProTracker. If it didn't follow this paradigm, it would be something else (could be fine as well, but it wouldn't be a tracker).
So, to sum up: trying new things: Yes (16bit stereo unlimited size samples and 64 channels are supported, for instance). Turning ProTracker into something that isn't a Tracker anymore? NO.
