I've never used it but from what I've read, Gobbler came and went for Sonar with X3. Here's what Seth from Cake had to say about it:
1. Gobbler dropped their support for Windows users at the end of 2014, a year after SONAR X3 was released. There is currently no Gobbler 2.0 Windows Client. There is only the legacy 1.0 Client. 2. Once Gobbler re-introduces a Windows 2.0 Client, we'll re-introduce a control bar module to sync with the their client.
3. SONAR X3 still works with the 1.0 client at this time. I would make sure all your files are backed up in a separate location just to be safe. 4. We had to make a decision to include it or not, at a time when Gobbler was still claiming users would lose all their data on December 1st. We didn't want to potentially ship a control bar module that had zero function or was broken.
Best,
