Alexey -
First of all - many thanks for all your hard work on behalf of the SONAR community.
I have a very basic question after downloading and trying this for the first time. My needs are very basic as I don't really have an elaborate control surface setup. ACT has been working ok for my needs with some minor issues.
I installed the 64 bit version of your latest dll into the shared surfaces folder (Program Files/Cakewalk/Shared Surfaces).
After restarting SONAR, "AZ Controller" is available from the pulldown list of ACT controllers. When I attempt to select it, it appears in brackets, and the In Port and Out Port I select do not persist as a selection option (this happens for any available MIDI port). At first I thought there was a conflict with an existing ACT controller on the same port I was attempting to use, so I deleted it, and another ACT controller on a different port, and retried, but the same thing happens. Any ideas? If I am doing anything fundamentally wrong (quite possible) please advise and I'll retry.
(Am I wrong in assuming I should be using the 64 bit version of the dll (SONAR Platinum 64 bit, Windows 8.1 64 bit)?
Thanks!
 

If you for some reason want to move it, you should re-register it since it is a COM object. If you do not know what COM object is or how to register DLLs, please, let it stay where it was... You can rerun the installation package to get it back. It install 32 and 64 bit DLLs and register them properly. The update/deinstallation is also are going to work only in case you let the installer to do its job.

This is looking promising but I am still not there with the control from my A&H ZEDR-16.  I can open the azslow plugin and see it is receiving MIDI signals from my console.  I am trying to get channel 1 on my fader setup so that I might copy the other 15 from its settings.  I have followed the instructions you have given but still get no movement in Sonar.  I know this is probably a stupid question but do I also need to go through the "learn" function by right clicking each fader in a Sonar project?

In case you see MIDI signals coming, that is a good sign.
 
I assume you are following "Quick start" step. Please check step (8), I mean you should see the control name in addition to the MIDI. And then check the order of actions: in the list, "Strip" should be the first and "Value" next. You should also see the actions executed in the Overview tab every time you move the fader.
 
Plug-ins are working apart from the SONAR MIDI Learn. As soon as you can see the code in plug-in, everything is right on SONAR side.

I got my fader 1 to control Sonar Track 1 level!  Some how I also got fader 2 to control Sonar Track 2 level!  When I proceeded to attemp fader 3, it adjusts Sonar Track 1 and not 3.  I am still a little confused by the sequence of the tabs and options to take to get all 16 faders programmed.  I have not yet tried the transport controls or the 12 rotary controls and 4 extra MIDI slide controls I have on my console.  The bright side is that I have seen some progress!

I am glad you have some progress and I appreciate you inform me.
 
In case you use fader 3 and look at the "Overview" Tab. Do you see "Track 1" before "Value" in the executed list or
you see something else? So, please check that that "Strip" Action for Fader 3 has correct settings.
 
I suggest you apply "Startup preset" with 16 strips as the starting point, it will define 16 sliders, 16 encoders as well as the transport section. It also can define buttons for strips and mode switching operations, but I have not found in the documentation either ZED send MIDI from buttons. That is not the show stopper, it is possible to adopt encoders/sliders to do mode switching (change banks, move WAI, etc.) or something else (move throw markers for example).

Hello Brett/Azlow3,
 
Not sure if this helps but there is midi information in this document on page 47:http://www.allen-heath.com/media/AP7236_iss_2.pdf which speaks to midi implementation on the ZED. Watching this one with keen interest. IHTH ...

I have overseen the page when I have quick checked it before, thank you for pointing it is really there.
 
So, 20 faders, 12 encoders and 17 buttons. If you have an idea what they should do, I can make ready to use preset for the device. While everyone can do this, the probability of head explosion during reading my documentation is not zero (especially for native English speaking people without programming experience )

I had hopes years ago that when they started working with and including Sonar LE that we might get a working preset for this unit.  While I love a challenge it has taken over an hour to get 2 faders to work.  I would gladly work with you anyway I can to make a complete preset for this unit possible.  There are many users of this console out there and many are Cake users, I believe even Craig A is one of us.

In case 2 faders are working, normally other can be done in 5 minutes. I see in your case something went wrong, and I can understand that can be frustrating.
 
So I propose you (and other) just write in words how you want to use the device and I prepare a preset which does that.
 
Please understand that I am not a professional sound engineer. I can not create genius perfect preset for ZED16 alone. I see ZED and CW have proposed to use it with Generic Surface and ACT MIDI. But since we have the discussion here, that is not what you want and it make no sense to just repeat that configuration in AZC.
