Re: [Csnd] [EXTERNAL] [Csnd] Code/audio Examples of filters from recent Lazzarini papers?

Right - but the reason I ask here is because I would not have known to look for "svn" in the manual from the paper, and it's not clear in the manual from which papers the opcodes come. (At least, I didn't see an opcode mentioned in the paper I read). That might be an interesting/helpful thing to add to the manual.

I will take a perusal through what is there though
