Thank you Joe!
I haven't received the keyboard yet, it is due to arrive on Tuesday, I will give them a try out then?
The PSR 530 and 540/550 are similar in features, and as mentioned above they are all a bit underrated as arranger keyboards, also the sound quality is very good. They are sought after on Ebay, and are snapped up quickly, so I was lucky to get one, they often sell for as much as £300.
Will let you know through this thread if the styles are compatible.
