What would you list as the primary BIG differences between the T4 and T5, musicforyourday (think I'm going to use MFYD!)?

Apart from the audio drums and multipads (we've discussed these to death and back!), what would you say were the largest differences?

The ensemble feature seems great, but only for people that know great voicing already, the effects are nice, but simply a slight improvement (IMHO).

But I'm sure you have a better handle on what differentiates the two, perhaps you could tell us what makes the T5 such a great leap forward?
