The Pa-80 is better than any other arranger in its solo section and having the option to load samples from triton makes it even more powerful but the styles and arabic kit on the vega is a lot better for arabic music so If you are good in programing and sampling then you can make the PA-80 have all the styles from the vega.
The PA-80 the way it is with that turkish arabic Card is only good for Turkish music and Iranian.
