I think Roland should do this in order to compete with Kurzweil, Alesis, and Yamaha but I don't think they will because it would extend the useful life of old product lines, and decrease sales of the new product lines. A lot of critics have commented for example that the Roland synth engine has not changed much over the years except for the Variphrase technology. Roland is out to sell new equipment, not make old equipment better. One question-is there a patent on the Expansion Card? If not why are there not any 3rd party mfg's? If so, Yamaha, Kurzweil, and Yamaha all rely on non-proprietory media for sampling. This card would have to be a RAM card and since there are no inputs except via midi, any sampling would have to be done through midi dump. In closing I would say if Roland was interested in meeting customer's needs, it will make this available. I for one would use the card to take the samples that I like off of all the other expansion cards and build patches on a custom card that I can organize the way I want.
