You could use those loops without EZ Keys, it's just the EZ Keys browser makes auditioning the loops very easy. It can be done but will be a bit more awkward and time consuming. I'm a guitar player and a one hand wonder on keyboards and I love EZ Keys. I use the Fishman TriplePlay if I need some tricky runs and stuff. EZ Keys is just so useful. Save your pennies every month and get it when you can, you won't regret it.
