Yes sure. I tested Studio Drummer recently and I honestly think it's a great product.
Together with Addictive Drums, it fulfills my "real acoustic drums" needs.
The samples themselves sound great, and as a "ready to go" instrument, it's perfect to lay out nice sounding ideas quickly, or provide the beat for a track your working on. For example, if you were building a track upon some piano or guitar, or even bass riffs, it fits well to provide a convincing rythmic part.
The included grooves are good, not the best I head, but as you can tweak everything, it's not that important.
The mixer is one of the best part of it.
The included EQ and COMP are using the algos from the separate SSL emulations for NI (Solid Mix Series). And they do sound very very good ! Actually if you need some quick quality Drums mixes, you can end up using only the included effects and they will have nothing to envy to your others effects.
The transient designer
included is surprisingly good IMHO, and the tape effect suprised me too. I thought like "well, another crappy addition to use it as a marketing argument", but in fact no. If you tweak it right, it sounds cool actually. Glues everything together and adds a nice vibe.
That just my views, as we all have different taste, but IMHO it's overall a great product. I would not have been again some "old school" drumkits, but maybe there will be expansions. I mean, it's modern sounding Drums, and it's good at that.
