i own cubasis 2 and just got a yamaha mixer that came with cubasis 2 le. the latter has a built-in offer to upgrade to the “full” app, but it doesnt say whether that’s to the current version, cubasis 3 or the old cubasis 2. i have zero need to pay for another cubasis 2, as i already have it.
the only thing i do with cubasis is scratchpad recording of practice sessions; if anyting interesting happened, i’ll send it over to cubase 10.5 and take it from there.
imho, owners of other steinberg products should get discounts for the relevant products they own, eg owners of cubase get discounted cubasis. at the very least, owners of cubasis 2 should not have to pay full price to upgrade to cubasis 3. as a cubase owner, i pay $99 when a new version comes out - much less than the $600 or whatever it costs wo that.
