Hello friends.
Excuse if this is in the wrong place, but I didn't find this particular keyboard here. A friend of mine have found a PSR s550 for sale, and wonder if it has USB, and If it can play Sff2 styles? I googled a little and found out that the model is from 2008. Anyone having it here? Or can say a little about it. My friend has a T5, but wants a lighter keyboard as a backup.
