This is an awesome instrument with lots of features and a great workstation.. HOWEVER.. it is not user friendly. The user's manual is your best friend since a lot of the functions are hidden within submenus and subcategories.
The memory card is not cheap so I'd suggest you go with a USB to save your recordings. With all this in mind, know that this is one of the best workstations out there, you are gonna love this 70lbs monster.
