Hi again.
OK if you don't see Alphatrack on the "Options -> Tweak current configuration" list then you're using the 'released' version. The Alphatrack preset has not been moved to the 'Releases' area yet, though I think Alexey will do this very soon - he was waiting on me to confirm that everything was working, which I did last night (there are still a few niggles, but it's perfectly usable as it is, and better than the original in that EQ control is fully functional).
Until he moves it to the release area, you need to go to Alexey's download area and go to the 'test versions' area:
http://www.azslow.com/index.php?action=downloads;cat=3 ... download that one, run it, then open Sonar and the plugin control window again, and you should see Alphatrack on the list.
It's not quite as simple as the original Frontier plugin, because Alexey's plugin is general-purpose (for any controller) and WAAAAY more powerful and flexible, but with the preset it should just work (or not, if your hardware has indeed gone south).
If you want to use it to test the touch input from the encoders, you have to go to the Options tab, select "Left Encoder touched" from the drop-down list under Hardware Control (or Right encoder, or Middle) and then right of that where it says 'System' change that to Rotary and press the Save button beside it. Now go to the Overview tab and it should give you feedback on that event.
'Strip' should already be configured to give touch feedback in the Alphatrack preset, as should the fader, turning the encoders and pressing all buttons. You can use this as a diagnostic tool to see if MIDI commands are coming in from the device for those events. If they are, and the driver is working properly, then Alexey's preset should be able to interpret them correctly.
Hope that helps!
