I not sure if this audio wav sounds vs. midi triggered sounds will be the next big thing. I listened to the demos (and I know that its a prototype) but I can't really tell the difference. I'm sure once the keyboard is ready to be released that there will more demos and the sounds will be great. I can only imagine the price tag on this puppy.
As I stated in my other post I had many ketrons and I do enjoy their sounds, but the reason I sold the SD5 was because the weight(very heavy), The guitar sounds and the drums were slightly better but no much difference between the XD9 and SD1. The same OS got to be boring.
I eneded up purchasing the Yamaha s900, 1. the price, a mini tyros for $1599. The sounds are great, guitars, brass, drums etc. and the weight, light as a feather.
I did look at the Korg PA800, but i owned a PA-80 and a lot of the smae styles are repeated and it was 1000 bucks more then the s900.
I guess time will tell, but I don't see the auyda being the next biggest thing that everyone will want to run out and buy. Ketron had that moment with the MS series and they were never able to repeat it.
