I’ve begun to gather the materials to port the Pure Data complex filter C code in the vcf~ object to an LV2 plugin. I have a working development environment (which happens to already have a cross compiler on it from some Raspberry Pi dev some time ago) and I’ve made it through a few LV2 tutorials successfully.
I found the following pedal in the default MOD distribution that I think could be a good starting point
I located a repository which looks like there would be source code to use as an example
But there is no source code! There should be a file called mod-bpf.c in that directory, right?
