Hi everyone,
The TranzPort should work fine in Windows 7 and in Sonar 8. However, I have heard of some issues with Sonar 8.5. It may be user error since there shouldn't be any major changes that should affect external control. I'm currently in the process of getting a copy to see if I can reproduce these issues.
You should all let me know what versions of Sonar you are all running and we'll see if there's a pattern here.
One more thing you should all try is to go into Sonar/Options/Conrtol Surfaces and delete the instance of TranzPort in the list. Then just readd it to the list (make sure the input and output are also set to TranzPort) and see if that helps. Sometimes in Sonar deleting and readding a device helps these symptoms. Other than that nothing jumps out at me. Also, for those of you reinstalling the drivers, just make sure that the USB transceiver is unplugged before you install the drivers.
