Just to add to this: I'm a heavy user of LP-64, to the point that it's in the FX Rack of most of my tracks, but all of those tracks are silent in Sonar (paid version) when I bring up my project. The workaround is to open the LP-64 effect and toggle the power button *on the effect* (the FX Rack's power off/on does not work). Once I do that for each track, everything is OK. BUT after I save the project and close Sonar, next time I open the project... same problem, and I have to repeat the workaround on each track again.
I'm not sure yet what other effects might be affected by this problem, but as I said, I use LP-64 everywhere as my go-to EQ.
Kind of annoying...
