CME UF80 / WiDI (wireless midi) version.    88-key hammergraded keys keyboard with expansionslots.


Cons:  Product quality. Good and Really Bad units are out there.  UF series seems better than U (first). 2 Keys that sound strange on mine (hits something inside) but thats seems to be a a common "problem" ;) 


Pro: Can be picket up for a low fee 2:nd hand (make sure all keys work first).  Expansion slot, and cheap cards as most sell them from overstock. 
Expanded with. 192Khz sound card.  (terratec phase 44).

Program used: Ubrain-beta 1.0 on XP/32.  Never got it worked/recognised in a virtuell enviroment, ie parallells on mac)


Widi (wireless midi) works natively via plug n play on both OSX 10.6.8 and XP and Win7. 
Audio (UF400 firewire):  XP = Vista driver 2.44,   Win7=vista driver 2.44 (32bit),  MAC osx=CoreAudio no drv needed.
The mixer panel under osx use rosetta, so from Lion and up, no goo.
