One man band hasn't been updated in 7 years. Xmure is more recent, but manipulates audio files, not really how an arranger works.

As I mentioned earlier, an arranger is a combination of three things: the arranger engine, the styles, and the sounds. This is where the software goes wrong. 1 Man Band expects you to load up a crappy soundfont. They basically ALL suck, even compared to say a Super Canvas. I certainly have never found a Soundfont that replicates all the sounds in a G1000, let alone anything newer.

This is why we need the majors to do this. They're the only ones with fully developed soundsets. A style player into a software Integra7 would seriously challenge most decent contemporary midline arrangers.

But the same style engine into a crappy Soundfont is going to sound early 90's at best.
