I much appreciate the very helpful comments here, but my Win 7 laptop (32-bit) refuses to download 64-bit apps.
My Equator, Seaboard and dashboard are fine, and I hope recently purchased Touch Block will work OK too.
But it seems I will miss out on the drums and studio player, and other 64-bit, Roli offers.
I prefer hardware, but am a humble Australian muso with three LPs trying to add computer music for modern variety.
Thanks again Folks!
