John it is what we are use to using ..that makes it seem easier..

Here is an example for you...Lets take a style..change a couple instruments in the accomp. Maybe add some effect changes, maybe change velocity of the drums...also get rid of the hand clap...change the pitch of the snare, and make some changes with the Eq on some of the drum instruments...Like the results..but I want to add 6 layer sound for live play..3 on the left side and 3 on the right...may be a 3 way split....Now I like the results, and want to save for instant recall....No problem with the made in Italy touchscreen on the G70...and it can easily be done in less than 2 minutes...now try this on the Korg..yes I know , some of the above cannot be done on the Korg, but do the best you can...let me know when you are done ..I am going to breakfast..will that be enough time

And if you are trying this on a Yamaha,,I will take a couple days off to relax..will that be enough time to finish on the Yamaha?

As I said for the most part it is what we are use too...but the edits on the G70 with touch screen are far better when you want to get the job done, especially on stage..

This will also be the biggest short coming on the BK9...

Touch screens rule..and when you add OS that can do the job..you have a winner..
