Today, after a two day struggle with Steinberg and their payments system trying to upgrade my Cubase Elements to the Artist version, I gave up.
Wanting a DAW with more functionality I decided to revisit Presonus (I already had the free version of Studio One installed).
On their site I found a special offer for the Artist version (their equivalent of Cubase Elements, albeit less specified in some areas) for Â£15 or thereabouts. I bought it. Then this afternoon I upgraded through their Crossgrade/Upgrade page from the Artist to the Producer version for around Â£80 - total cost, from scratch, of the Producer version less than Â£100, the discounted price on Thomann being around Â£130.
That I reckon is a very good deal indeed
