Are all Cubase updates paid for?
Any maintenance updates are free. For example, with Cubase 7 they went all the way up to 7.07, all of which were free.
Then 7.5 went to 7.5.10, .20, .30 & .40.
Now 8 Pro is up to 8.0.10, .20 & currently 8.0.30.
So one would [or would have] paid for 7.0/7.5/8.0/8.5 [and 9.0 when it comes out most likely next Dec.] but not the sub-number updates [fixes] in between.
