I absolute agree with you! Not even the poor and buggy preset-management of Mg Modular V or MiniMg V has been optimized. Not to mention the cpu-hunger of spark vdm which is still very high. Same with the sonic capabilities of some synths (Arp2600) which sounded good when they were released a few years ago, but seem outdated now compared to other new released va-synths.
I know what you mean about the pricing, they have dropped the price which means some people are going to be pissed if they bought the old version less than a month before.
But there has to be a cut off period for sales and a cut off period in which they keep these offers. It's not like Arturia are the alone in this. Apple for instance, they don't give a flying f**k about their customers, someone can walk into a shop and buy a MBP and the next day they could release a faster one at a cheaper price and Apple wouldn't take it back. It's just the luck of the draw right?
As far as the bugs.. Yes there are a few, but once you know what they are, just work around them, the preset naming is a pain at time on the Mg stuff yes, but it's a drop in the ocean to what guys have had to put up with with other software people. Avid for one.
The ARP 2600 isn't as great sounding as the TimewARP 2600, I do prefer the sound of that to the Arturia, but i don't get CPU hogging with the Spark. If you're running pro tools, it's more likely Pro Tools, PT's has never liked VI's and probably never will.
