My JSFX plugins are purely experimental and i don’t think it’s suitable production. That was so long ago, it was time when i was started learning about programming especially digital signal processing.
If you referring plugins on my project page, those are VSTs not JS. I use them all the time, especially for JRENG! music production. However i don’t have plan to commercialize them because i don’t have the time (and resource) to maintain the development. Those plugins only available on macOS VST format, i don’t have other machine with different OS to compile the binary.
