I have got this card and of all the pianos on Roland arrangers/synths this is my favorite. Interestingly I have not installed this board though in my setup because I found that if I took the patches on the SRX-11 and revoiced them using the internal samples of the Fantom-X piano that there was really not a lot of difference in the resulting sound and infact I actually slightly preferred the revoiced patches because they were very slightly brighter.

Best Regards
Paul.
