Thanks to you all for your input.
I love the Lab 49 and have several of the soft synths loaded and all work fine, that's why the issue with Spark and their tech support reply through me a curve...
I'll try ditching the VST3 and see if the VST2 works.
John - is your Spark VST version 2 or 3?
If 3, have you loaded Spark as a synth track in Sonar X3e, launched it from within Sonar X3e, and it syncs fine with SparkLE?
And no issues controlling it with SparkLE?
Stand- alone works flawlessly, but Spark in Sonar can't see the SparkLE controller.
Let me try VST2 this evening to see if thats a good work-around.
Thanks again to you all for your feedback.
Cheers,
MG
