In the assets i see the source code, winamp version source code zip and source code tar.gz. Maybe it will be great to add also just jsfx version. I got it from the sourcecode as I am somewat familiar with Github.

@Derek Lane I tested the DSP version inside SPL. It works fine, SPL shows the controls. What is interesting that it shows edit fields not sliders but that is probably caused by the spl internal dsp rendering.

@Derek Lane I noticed that Optilab core now adds little fade at playback start or render. Is that intentional expected behavior?

@Derek Lane yes, jsfx inside reaper. The best way to test it is to add some noise on master track or monitor something via armed track. It fades when you pause or play. But you can also see it in action on projects where the drum starts immediatelly.

@Derek Lane that sounds great
