Zero. I use the keyboard as a tool to write. If there is something I want to play but I can't I will slow down the sequence and play it. I don't have the patience for rote excersizes. I studied some theory and scales but never learned to play them fast (thanks to sequencers). I was an organ player i my teens and twenties and coupld play all the solos from Santana and a few covers on a C-3 I lugged around. But Since the sequencer came out I quit playing live nad became a studio rat losing any chops I had. Oh well. Its fun not a living for me.
Every hour I spend playing anything is "practice" except Im doing what I prefer to do rather than what a book or teacher dictates I should do. SO far I have not found it to be a handicap. Especially with these Arrangers.
I'm used to workstations where one has to play every part. These Arramgers are a cakewalk.
In fact I use it with Cakewalk....
