You can't import samples into the JV2080 or any JV synth for that matter. But a few years back there were a lot of small companies who build in that option into 'regular' synths. But what I've learned from those developers is that Roland doesn't want to give other researchers their blueprints or any information of the synths so for the Roland I never saw any of that kind of equipment. I don't know if Roland has changed in that matter. Check the 'Frankfurter Messe' fair or any other big fair. 'cause on the big fairs you will find a lot of small companies who build those type of gadgets for synths and stuff.
