I have both V-Control and AC-7, the former won't work on older wi-fi routers that use old protocols and the latter is frustrating sometimes when trying to handshake.

That said, of the two, its definately V-Control for me, now i've changed router.

Cheers,
Jerry

The fix posted here eliminated the handshake issue with AC-7 for me.

Noel says a proper SDK and several fixed dll's are coming as well.

I use DAW Remote HD. I can use it to easily track my drums by myself. I can't do things like control buses and such, but it works really well for my purpose. It's only $15 and has a Sonar Template, along with having the ability to customize.

I agree with bandso, a Sonar specific app build by Cakewalk would be great.  

I like V-Control Pro, but believe it or not, for controlling the transport and arming/disarming tracks for record/mute, etc. - I'm still using the trusty ol' Frontier Tranzport!

I paid the $50 thinking V-Control Pro would allow me to control my headphone sends via Sonar's busses, but alas, it does not have the ability of scrolling down several sends within a track...

In desktop mode you can see the top two sends, but there is no way to scroll down to see the others.

Think of being behind the drums, recording your digital kit, a bass guitar, an electric guitar, and a harmonica (all direct), and one mic for guide vocals.

The bass player wants more kick and less harmonica, so you get up, walk over to your PC, adjust the buss sends accordingly and sit back down behind the kit.

Now just as you sit down, the guitarist/lead vocal would like more bass...

This balancing act goes on for a while until everyone is dialed in for the song we're working on.

It would be utterly fantastic to be able to adjust those headphone sends from out at the kit.

If anyone knows of an iPad app that will allow me to scroll the sends, PLEASE LET ME KNOW!

For that matter - it'd be great to be able to use the mouse wheel in Sonar to scroll up and down the sends!
(Maybe when that happens, V-Control Pro will be able to do it as well.)

In the mean time, I guess I'm getting my much-needed exercise in!

V-Control Pro.  Without a doubt, one of the best purchases I've made in years.  It's even more bang for the buck if you also use other DAWs (e.g., PT, Cubase, Logic).  Lemur is nice as well, but much higher maintenance IME and works far better as a MIDI controller or custom templates than as a control surface.

Search the App Store for "Microsoft Remote Desktop". There are 2 or 3 free apps that allow you to connect to a Windows computer using Microsoft's Remote Desktop Protocol, which is a pretty low-resource way of seeing the screen of your DAW on your iDevice (rather than a control surface emulation).

Free, Remote Access Application to your PC. Works wonderfully. Forget control surfaces, this gives you access to your SONAR display - just recommend judicious use of Screensets to make it work more effectively on the smaller iPad screen. Perfect for not only controlling but seeing what's happening in SONAR when you are recording remote from the DAW.

One more vote for Cakewalk to build a remote app! It seems that more and more DAW makers are doing it and, it only makes sense, to me.
