Hi Hennry,
The current, protected "now free" Expansion Packs from Yamaha (.cpf format) can be installed on every Genos (and of course all unprotected .ppf packs as well). However, if you have older, paid Yamaha packs or paid third-party packs installed on your current Genos (also in protected .cpf format), you CANNOT install them on another Genos, as such packs are associated with a specific Instrument ID (.n27 Instrument Info file).
Best regards,
Chris
