If BIAB goes to 64 bit I'll upgrade just like I did Win 8 then Win 8.1 For those of us who use BIAB for accompaniment on gigs it probably won't make any difference. All I need for background are bass, drums and occasional guitar. I'd be willing to bet that a large number of users are using BIAB just like that, especially long time users. I personally know some pianists who use BIAB the same way I do. The main emphasis is on my playing, not BIAB. Later, Ray
