This is a welcome update because the DS2416 mode in Logic offers one of the easiest ways to access the features of the DSP Factory. Before this version you could not use DirectX plugins in this mode so if you have not yet upgraded here is a good reason to do so. Logic 4.1.1 totally replaces its software mixing with the hardware mixing (and other functions) of the DS2416 so, if you want to get the full functionality of the DS2416 in Logic 4.1.1 you will have a few restrictions on the number of plugins you can use but thanks to the 4.0.4 upgrade you can use 4 DirectX plugins on each DSP Factory channel even when operating in DS2416 mode. If you need to jump in quickly but don't want to get stuck with a dog of a sequencer you will need to quickly trash then Musicator is the program for you.
Probably the best compromise I have seen between power and ease of use.
