I'd pay attention to the loading aspects of it. You can't have more than 4 SRX expansion cards loaded at a time... that seems to imply you need to load the SRX card IN ITS ENTIRETY just for one sound. Not very efficient. Personally, I think they should have simply added all the waveforms to the basic ROM chips and not made you jump through this unnecessary hoop.
It also appears that not all the SuperNatural Tones are loaded from the git-go (look at the SRX loading splash screen), so once again, not all sounds will be available instantly, and not all sounds can reside actively at the same time.
There seem to be quite a few 'gotchas' if you look carefully.
The weird thing is, how many of these sounds are already in current and previous gen Roland arrangers. So many of you are gushing over this, yet somehow weren't exactly glowing about the arrangers! To my ears, this sounds like a Roland. Not exactly a radical departure from the G70/BK-7m sound I am already used to.
There's some nice synth stuff, and a few (but not many, IMO) of the SupNat voices are good, but the core of it is Roland, all the way.
Why are opinions so different? Or is it simply 'new gear syndrome'?
