Thank you! Although documentation errors can be confusing, we can resort to printing to check properties or functions. I often read the documentation before printing.
On the other hand, I am reporting some stuff that I think needs to be addressed within the API. I do not intend to bombard you with new requests. I’m trying to build a fairly comprehensive tool that covers a lot of things related to all effects devices (track, sample, or modulation, …plugins) and it’s missing properties that are supposed to already be available, among other details.
Edit: This has been fixed in R3.3.0.
