That was not meant to be rude. I prefer to call it the original as you said.
Forest, I didn’t use the original implementation a lot, but it is well documented here : http://www.csounds.com/manual/html/lua.html, and it also is more robust and battle tested.
The implementation I made was mostly designed for simplicity, in a time I needed to quickly access Lua tables for composition.
Both should now be relatively easy to build since based on CMake. So if you’re on linux :
mkdir build && cd build
Then you just need to move the resulting binary (.so) to the csound plugin64 directory (probably /usr/local/lib/csound/plugins64)
Um, instructions re how to install and use csound plugins?
