Don,

what other arranger, besides AUDYA actually has a HD? or a HD which has parts of styles that stream off of it (drums, bass, guitar)?

i know my G-70 does not have a HD,
but it DOES have a nice cover where i can EASILY access my expansion card,

i mean ROLAND was smart and thought "maybe the customer will want or need to quickly access/swap the card.

i just removed cover once to install expansion, only once, but it's EASY

i did not have to open up keyboard

same with AUDYA, it should be easy to swap out HD, it's not an expansion card, but you may need to access the HD MORE times than you would an expansion card...
