I can't test it today because I am down with flu and stay home. If anyone of you had a chance mto try it in win 10, I will be glad to hear from you.

Saved me creating a post about it. Time to go back to Win10 soon perhaps :)

YES! Win 10 looks like an improvement to me. Faster start up and reduce latency. 

ACT working?

It is sort of working but a bit different. First after you had installed the driver, be sure to switch off and on APRO. Then press the ACT switch on APRO. At Sonar's Preference (Press P) page > midi> Control Surafces, you can toggle between APRO 1 for soft synths, and APRO2 for Sonar's tracks fader/panpots or PRroCHannel EQ.
 
I had so far tested 4softsynths with ACT, 3 of them works, (Alpha CM and synthmaster and Zeta2) and one is not (Harmor). ACT work best when you engage the recycle plugins window. ( Preference (Press P) page > Vst Settings> General>).
 
This is only a 15 minutes test. I have not tried any effects plugins.

Wow, the editor is here too!

Great - my suspicions were that the overview Win10 document was preliminary and it still is. There are still many devices missing from it (I'm looking out for my Octapad for instance, this will probably go on for months). I can't imagine the plugin will return as it's not really required.

Thanks for feedback about ACT.

Here is the page for the A Pro Editor download.

After I restart my computer this time it work like a charm. I did not activate ACT.Just select APRO2 in preferance. It worked like a charm like the old days.

Good built in Sonar code still works. Thanks this is good news all I have to worry about now is my Octapad and Yamaha keyboard. Very useful feedback thanks.
