For the most part, you can accomplish the features of the H910 with the H3000 Factory, apart from the keyboard (as you mentioned).
However, while you can recreate similar effects, the original H910 has a very specific and recognized character to it's pitch shifting and converters, which were modeled in the H910 plug-in. Specifically, the lo-fi "glitching" that happens when pitch shifting, the primitive converters, and the inherent randomness of the hardware. So, the sonic footprint of the H910 plug-in is in fact quite different than the H3000 Factory plug-in, which some consider a "recognizable" sound.
Hope that helps!
