It's Alot of $$
but nobody is forcing anyone to buy anything

this upgrade is mostly about new features
you don't want or need them, you don't buy them

yes AJ seems to have also Addressed the timing issues with audio drums
something Ketron should have done for free

again there will be OPTIONS starting at $499

not sure how much time was put into this project but I assume a lot
time is money

but ye I agree it's expensive as heck.
