Since the Roland E-100 and E-200 are in fact the EXR-3 and EXR-5 (with a different finish, that's all), it should be possible to load the EXR-3s/5s upgrades into these models as well.

Since we don't have the E-100 and E-200 here in Europe, my question is: Is there anyone out there who dares to try to upgrade his E-100/E-200 to a EXR-3s/EXR-5s? I'd like to know if that works too.
