This whole A-Pro thing is still confusing to me. All I know is that when I first got the keyboard, I set it up according to every instruction I could find, and while I've been able to control Sonar with it (faders, pan pots etc) there has never been a connection with ACT. No lighting up of the ACT button on the keyboard. Also, as said before, I usually need to go back into Sonar's preferences and set Apro up again as my control surface because that info is dumped.
Basically - it works, even though nothing with ACT actually works. Hmm.
I need to answer your questions
Jlien X:Jlien X...Are the A-Pro and PC connected via a USB cable?
Yes.
Jlien X...Do you also connect other devices via a MIDI cable?
No, I haven't used MIDI cables for quite a few years now.
Jlien X...launch A-PRO Editor and try to have the editor receive one of control maps from the A-Pro hardware and then transmit the map back to the A-Pro hardware. If the LCD says "Receiving..." then your A-Pro has no problem receiving a control map from the PC, right?
Right - That works. It's only in Sonar that exchanging maps doesn't work.
Jlien X...Is your Preferences > MIDI > Control Surfaces page set up properly as shown in the document in Alex's post?
Yes, seems to be. That's a really simple setting window to work with. That's the one I usually have to diddle with every time I launch Sonar.
Oh well. I've had this keyboard several years now - It's always been like the above, just 1/2 working, but I'm not too bothered. It's doing what I need.
