If you install my controller: http://www.azslow.com/index.php/topic,163.0.html , I can assist you to find the reason of your problem (may be solve it, even in case it is your specific device bug).
Note, it is not that I ask you to install "add-ware" for help
Unlike with original plug-in, it will be possible to see what exactly is going on in respect to MIDI messages exchange and logic. From your description, I can guess that "Touch" signal is "unstable". Even if you see the light is always "on" while you are touching the fader, it can happened that it periodically sends "off/on", too fast for led flickering but sufficient to instruct Sonar to reset the value.
(do not forget to remove FaderPort plug-in from Sonar Control Surfaced when using my plug-in and remove my plug-in before inserting FaderPort back, they do not work in parallel. Also I remember that fader port power cycling is may be required when changing plug-ins).
I checked out the page but I am a little confused about the actual installation process....do I still go through the command prompt/setup as recommended by SONAR documentation? It's my understanding that those steps are necessary for the Faderport to even be recognized in SONAR.
(I actually uninstalled Faderport recently so I'd be starting from scratch...there are currently no drivers installed.)
What you're describing sounds accurate...that the Faderport is sending on/off information even if it's indicating that it's still writing Touch automation.
I didn't mention this earlier, but there doesn't appear to be a problem with SONAR itself in regards to writing automation. If I record an automation pass using my mouse, then record another pass, SONAR maintains my automation value until I release the mouse, then it jumps back to the previously existing level, just as it should.
I'm thinking about picking up the X Touch (even though it's frustrating that one has to ignore the button labels printed on the unit since they execute other commands within SONAR), but the main purpose would be to write multiple lanes of automation simultaneously, so I'm trying to determine if there's just something wrong with my Faderport, if there are things I'm not doing right in regards to setup, or if this type of behavior is to be expected with control surfaces within SONAR. I've seen some grumbling about limited support for control surfaces on this forum so wanting to figure out what's realistic before potentially dropping $600 on the unit!
Anyway, thanks for the info...we'll see what happens.
