Hi
I currently have the VS700C for sonar. As you may know the support for this pricey gear dropped just about 2 years after releasing the product which makes buying it the worst decision in my studio upgrade process. With Platinum and win10 it seems that the console is buggy and not functioning correctly,putting aside this fact that the device had a lot of issue even with win 7 and sonar 8.5 
As you see all the major DAWs can work with some dedicated or general console and most of them are big enough to be considered as professional setup for commercial studio. Just to name some:
Pro tools with C24
Nuendo and Cubase with Yamaha Nuage
logic, reason, reaper, ... with Icon Qcon Pro
................
it seems that SONAR is out of competition. WHY?? I asked Icon about compatibility between QCON PRO and SONAR and they said no due to some protocol restriction inside Sonar.
I want to know if there will be a professional console for Sonar or at least can Cakewalk implement  some other protocol regarding control surface so that we can use the new products in the market rather than old Mackie MCU and buggy VS700C ???!!!.
 

I'm using a Behringer X-Touch.  It works in Sonar, Studio One 3 and Ableton Live 9 (what I have).
 

I've got the X-touch as well and it is very functional.  You will need an overlay to label the buttons correctly (but you would with any other software othan logic.)

Hey fireberd and Dave,
 
I've been seriously contemplating a control surface for my home studio setup. I was thinking about the Faderport 8 at first, but with the seemingly more rich feature set and recent price reduction ($449) the X-Touch has caught my eye. In addition to SPlat, I also use REAPER and recently purchased Studio One 3 (at deep discount). But my main use would be with SONAR & REAPER and I am concerned about compatibility, reliability and support. How are you both getting along with the X-Touch using your studio environment and do most of the surface controls work with the aforementioned DAW apps? I have often read unflattering things about Behringer products, but I am intrigued with the feature set and low price point. Thanks ahead for any input you can provide.

There are several threads regarding the X-touch.  I bought mine about a month ago based on those.  The set up was very easy and the controls, while not labeled correctly for Sonar (or Reaper or StudioOne) on the unit, are very useful.  A template or overlay can easily remedy this.  I have had nothing but good results with it.

Behringer has gotten their act together lately.  I used to be on the "no Behringer" bandwagon but many of their new products are as solid as any other brand.  I also have a Behringer Power Play XL, 8 channel headphone amp that works great.  The motorized faders are "dead quiet" on my X-Touch.  As Dave noted you really need the overlay (I have a jpg that can be printed out and used) for some of the control functions. 
 
Both Studio One 3 and Ableton automatically detected and installed the X-Touch.  I didn't have to do anything.  In Sonar there are some manual steps to get it set up (Sonar automatically detects it but doesn't set it up like other DAWs).
 
 

Thanks guys for your added input! There may be an X-Touch added to my setup in the not too distant future.

Does everything function as labeled in S1?

I don't use all the X-Touch functions.  Can't say what all works or doesn't work in any DAW.  Both Studio One 3 and Ableton that I have were freebies for buying hardware.  I don't use them for any production work.  
 

As regards the OP ... the vs700 is still the best you can get when using sonar. I was just as shocked when they dropped its support so quickly but mine still works fine here. It has far more control features than any other available CS and I even extended its functionality by assigning features to unused key combinations via MIDI translator

My advice - hold on to vs700 if you already own it. There is nothing better out there for sonar ... and cakewalk is totally ignoring any CS functionality requests. So nothing will change here.
