I have a roland rd700 (not sx), and I`m whondering weather there is any point in buying a srx piano card uppgrade for this keyboard, or might the
piano patch in the rd700 be similar in quality to the srx piano card?
The Roland SRX-11 expansion card contains a new set of piano samples, also introduced with the RD-700SX, with the primary patch being called "Superior Grand". In my opinion, it is the best piano Roland has ever done, and would be a worthwhile upgrade to the original RD-700. I'm less fond of the SRX-02 Concert Grand card, which dates back to 2000, and was really superceded by both the Fantom-X piano and the SRX-11.
