Frank and Zuki, I think you are both correct.
Here in my store, most folks think just like the two of you. Ketron has tried to duplicate the type of Mega or RX voices used in Korg and Yamaha keyboards by adding squeeks and fret noise on the guitars. Unfortunately, they don't use velocity to add and swtich the different elements but rather sample secific "noises" on lower or upper octave notes. By doing this, they are able to create pretty good guitar patches within a style but to just play the sounds, there is much lacking.
Also, there are so many fewer styles, especially in the Big Band and Jazz catagory compared to the SD1+ and when you load the extra SD1 styles into the pattern memory, the sounds just don't sound the same, because many of them are different or just missing.
So it leads me to say the same thing I told the owners of Ketron over two years ago when they were demonstrating this keyboard at the NAMM show. "Price it at the Yamaha PSR3000 price range or don't expect to sell very many here in the USA". They didn't listen to me!
As for a factory reset. You can only push the button "save/enter", go to power on setup and select "default" to put all the factory settings back to "out of the box", but you can only do a style default to put the factory sounds back to their originals.
