Neyrinck V-Control Pro Users???

No you can use it as if it's a mouse, although you'd be a lot quicker with an actual mouse ;)
The main thing I don't like is that you have to keep adjusting which part of the window you want to see. But that's more of a workflow thing, the application itself works great, I use it a lot when I'm tracking myself. Definitely the best I've seen, and kind of a wonder how well it works considering Sonar's shakey Mackie Control implementation.

You've described how it works and my problem with that perfectly ;)
And yeah even if cramped it's still really useful. Even if it's just to see if your recordings have clipped, where exactly you are in your arrangement, if you need to adjust an effect, etc. It's by the way a full shared desktop type thing so I can for instance also add some reverb on my E-MU Patchmix app (proprietary mixer app for my soundcard with zero latency monitoring and basic fx).

I use it as a transport, remote and virtual screen when I'm at my drum set. Works great for that!

It does require that it is accessed through a wireless router to be able to provide wireless operation but the router doesn't have to be online.
 
We have an in studio network that is just for project backup and has no internet access so there is no obvious hit in performance for Sonar like there would be if programs and apps were constantly trying to update themselves online.
 
Connecting to this was a snap with the included Neyrinck driver, worked instantly with literally no setup. There was much more tweaking with the other rtpMIDI based apps ( Touch Daw, Daw Remote HD, AC-7 Core HD ) to get them to work and each one has had odd behavior quirks that V-Control has so far not exhibited. This is not an endorsement, just an observation.
 
But like all things that "just work well" there seems to be that obvious correlation between performance and price ( 50 bucks!!!! Yikes )

I am sure the issue was something with my router and/or home network.  But even ad-hoc i could not get v-control to work.  Ad hoc finally worked with Ac-7, so that is the way I went.
 
I had the exact opposite experience as Featherlight with neyrinck and did not get much help on their forums so I dropped it.  I would definitely try the free ones before I spent any money at the APP store.
 
As an aside, the rtpMIDI software you have to install on your PC for AC-7, also works for most other Ipad midi apps that are available.  (there are quite a few.....) You also have to install apple bonjour.  (or the full itunes, but I hate itunes so I just installed bonjour)
 
Once you get it up and working seems pretty stable, only annoyance is I have apple software on my DAW... Arrghhh!

I tried out the free version.  I wasn't impressed with the free version and the program that you have to install for the wireless interface requires the PC to be on line.  I didn't like that and rejected it. 
 
I have a Frontier Tranzport but have been having some flakey problems and looking for a potential replacement in case the Tranzport dies and the reason I tried  the Nyrick.
 
 

No, it doesn't require the PC to be online (as in, connected to the Internet, if that's what you mean). It requires a LAN network, so you just need to create one with no Internet connection, disable the Internet connection and antivirus software, enable the new connection, connect the iPad to the new network, load up the Ney-Fi software on the computer, and away you go. Pricey, but it works very well with Sonar.   

Multiple posts! Sorry. Not trying to get the post count up!

you can also go ad-hoc network (no router) and connect ipad straight to PC wireless.  (lowest latency, but cuts off all other wireless access....though when you are recording this is not a bad thing) V control and AC-7 support this. JR 

Yes, I'm doing that (maybe I didn't explain correctly) using a USB LAN adapter. Only the iPad and the PC are on the network.
