This is mainly useful for live performance and lazy orchestrators, but I could see myself eventually 'building' a solo violin for instance that would change articulations (using 'Lanes' in MC6) according to the velocity of the note but that would be a hobby in itself So a good solid B for the interface. The powerful sample tank interface also allows you to split the keyboard between 2 groups of instruments and also will play instruments according to the velocity a key is hit (example: the faster you hit the key the more instruments play). They might be really good, but are lacking any presets that I could see so you have to experiment on your own. MP uses it's own version of the IK Sample Tank (free download) which is a very powerful tool in itself giving you control over almost everything in the sounds you want to tweek (and a lot of things that are best left alone, so remember where the dials where before you started playing with them, or reload the instrument after you've totally messed it up) There are also quite a few effects included that could be applied to each instrument or instance of MP. I promised to do a somewhat in-deph review of IK Miroslav PhilharmoniK a couple of weeks ago, but wanted to wait until I was familiar with it in MC6 so.
I know this belongs in 'plugins' but it was discussed on this board so I'll start it off here.
