I'd like VST3 support if only to do away with that awful plug-in manager.
I don't even think it is for the vendor of a host to quibble the technical merits of VST2 over 3 it's more of a thing for the third party plug-in developers to worry about.
If it's good business for THEM they will eventually stop developing for 2.4 in preference for the newer VST 3 anyway. So however much the host vendor applauds the functionality of the older technology it won't be of much use when everyone has migrated to a new host that does support VST3.
I gather it's on the horizon though however distant that maybe.
I wonder if they've even got Rewire working properly in X2 yet? That would be a breakthrough on it's own after several long years.
I still like Sonar and am planning to upgrade this cycle, but my reliance on it seems to diminish further as other vendors steal the march on these things. I've been using take lanes and Rewire via other solutions for a couple of years now as there is still no one DAW that covers all the bases for me, but when I consider that Sonar pretty much was the major part of my music production flow compared to the secondary functions it has for me now I can't help wondering how well the method for prioritizing for engineering resources mentioned earlier is working.
I can understand how the upsell of the included semi-versions of Breverb, TH2 and R-Mix might generate some income from the faithful but I wonder how much the omission of technology such as VST 3 will put off new users coming into the fold or fail to tempt back some of those that have jumped ship in the last couple of years.
However much those that don't like the idea, Sonar is certainly in a minority as far as DAWs go in lacking VST 3 support. Not that it really matters to most.
Yet!
