With almost 20 gigs under my belt so far using the KORG PA3x I know I made the right choice!... WOW!! is all I can say!!
I haven't even begun to scratch the surface of what this incredible Arranger KB can do as I had to rush into the Xmas season and perform with it in a mere week. But come January after the holidays when I have more time I will dig deeper and explore the OS even further, try the CS feature, and see where all this takes me. I'm learning new things every time I play it, I'm proud of my patience and desire to learn more as I was stuck in that "MOTL" mode for a while..lol...more to come...
