I have a Fantom 6 and I had installed the Jupiter 8, Juno 106, JX-8P and SH-101 models which were available as a promotion I think when the synth was first released. These are also accompanied by expansions for presets I presume. Since the EX upgrade has ACB versions of the Jupiter 8 and SH-101 I would like to uninstall the earlier versions as I don't see any point of having both versions taking up memory space. Does anyone know how top do this? Thanks
