You can create one yourself. You need to install the Kronos editor 3.1 (if you haven't already). Then, let it sync with the Kronos (so switch it on first and make sure it is connected via USB).
Once it is finished, go to the global page in the editor, and on the right hand side, you will see "create program names file". One of them is SONAR ins... The good thing is that it also takes your custom progs or combis...
The editor isn't much use as a VST in 64-bit apps, but on its own it isn't too bad :)
