Dave is cranking v4 code. He and I are talking daily. You will probably see a release in February/March timeframe. I was just testing the feature of adjusting timing marks between effects. Dave made it so you click and drag the timing mark between two effects. I will no longer use audacity to make manually marked up files. I will still use the audacity plugins to get beat and bar timings. I. Have written the first pass at a converter for xl 3.6.x files into xLights 4.x. Those converted files do open and layout all the effects in the right place. We do not have the render effects engine connected. At Dave's frenetic rate , that may happen in the next two weeks. Ui changes to 3.6 are now frozen, we may release fixes to effects. Be prepared in the next month to see the new XL 4. It is pretty awesome. Dave came along in late October and gave us opengl. Xl 4 would not have been possible on the old graphics engine. With that building block done, he gave us whole house models. He gave us the ability to click on objects in preview. He took 6 weeks off to get a show. About a week ago he picked up xl 4 again. Dave, thanks!
