Well it tries to be a pro-audio sequencer rather than just a tracker.
I can see nothing whatsoever in common with what you have there *shrug*
I've used it since it was just MED. Octamed SS's interface is a natural evolution from v4:
If you look at v4, it's an oldskool tracker interface (which is fine, I grew up with it).
http://xmp.sourceforge.net/gallery/octamed-4.00.pngIf you look at v5.04, you'll see that it's almost the same except that it's been reworked in GadTools. That has resulted in a lot of repositioning of the controls, but fundamentally it's the same:
http://donbuche.com/sites/all/imatges_web/octamed5.jpgOctaMED 6 simply took this to it's logical conclusion, separating related sets of controls and putting them into their own windows that can be repositioned on the screen to wherever the user wishes.
OctaMED SS GUI did not change from v6, except to add a few new windows pertinent to it's new mix-mode playback.
The notation editor that appeared in OctaMED was (IIRC) removed by the time SS came out since nobody used it and nobody missed it. It remains, and always was, a tracker. Just because it destroyed the 4 channel limit and shrugged off all the limitations of it's old 5-8 channel modes didn't change the way you create music with it.
