I am not feeling 100% at this time but I thought I would offer people a choice of listening to both, as it seems that is the BIG question I'm reading and hearing regarding these resources... Yes I did try the resources early on, but as I posted afterwards I didn't feel there was much of a difference, which was MY honest opinion alone. This is why an A/B comparison is important especially when people are laying out money or donations, etc.. But out of curiosity I gave it a try of which I appreciate. It just still seems to me that any player including myself has to spend the time to get his/her keyboard to sound the way THEY want by putting in the homework and time to make that happen. The way an instrument sounds is a very personal thing that only the player can achieve, there is NO magic program to make it drastically change unless your yourself put in the time to make it that way.....what one person likes & hears and needs is the total opposite of what the next player does. I too would like to hear some of the others who have used it offer A/B comparisons also.Korg arrangers have more then enough features to make any of them sound the way YOU want. I have been working with my KORG Pa500 for at least 40/50 hours and now have it sounding almost to my standards for stage performance of which I am totally impressed & satisfied with my purchase. Thank you for the well wishes.
