An 88 note fully weighted synth workstation. Great sounds on board, augmented by the kore64 expansion card and also including the sounds from the sweetwater pc3k expansion and several extra piano sample packs I've bought. Housed in a lightweight gator case. A few white marks on one end (detailed in picture), but end caps can be replaced for around £30 from the distributor if you're bothered about this, doesn't affect operation whatsoever. Support network is great with kurzweil products as well. Fully compatible with all k series patches so if you're moving up from an old k series you can import all your old sounds. Tons of sites hosting user created patches. Get in touch if you want any more information. Would prefer someone to collect but will post if necessary.
