While I don't know the exact size of the Mixvibes company, I think it is safe to say they are not in the Pioneer/InMusic/Traktor/Atomix category.
Also, where in the past they could be dedicated to just Cross on PC/Mac, they branched out to iDevices and Android (in fact the first truely workable DJ app for Android). So that increased the amount of places to work on, with - I suspect - no or little increase in staff.
Then they came up with RemixLive and RemixVideo, all for Mac/PC/iDevice and Android. And granted, it seems those are doing very well.
So, it's not to surprising that development of a new Cross version has been moved to the back-burner.
Am I happy about it? No. Do I feel there is a burning platform for them when it comes to supporting all this great new gear coming out? No.
I get it, yet at the same time it would be nice to inform the user-base of their plans.
Mixvibes is great software that certainly until recently compared favorably to other mainstream DJ software. But new software has entered that market and existing software has improved itself more than Cross has. It is also software that is sold at a very very competitive price. And since I bought it at version 2.4 or so, I have never had to pay for any upgrades.
Now, you don't need a major in economic studies to understand that this is a business model that is not gonna sustain you for long. Only way to get new money in is through new users. Existing users don't bring in any more money! So, as a company, where are you getting the money for further development?
It's no wonder that a lot of competitors are either raising prices (lifetime license for VDJ is a lot of money), making money selling key features as paid packs and/or moving to a subscription model where you pay a small amount every month and in return get the full product with all the features and free updates/upgrades. One particular company uses their own DJ software to help sell their own hardware (actually two of them do now), by giving away full version of it instead of the LE/Lite/Intro versions you get with many controllers.
So, yes, I get it. Doesn't mean that situation should continue though. Hopefully steps are being taken behind the scenes to pick up further Cross development now the other new products have come to market. It would indeed be nice to hear something on the issue from official Mixvibes representatives.
Just my 2 cents as usual.
