Accessing parameter links in Lua?

[madskjeldgaard]

hello all

I'd like to write a simple script to automate some of the parameter linking that I do a lot of, but looking through the (lua) Api, I can't seem to find any mentions of parameter links. How do you guys access parameter links on fx?

Thanks

You have to use text state chunks, I guess.

Ah yes, I saw MPL (I think?) do something like that. Is there any kind of documentation of text state chunks out there? The apis seem to only mention them briefly.

You can find docs for TrackStateChunks and EnvelopeStateChunks in my Reaper-Internals-thread:

BTW, can you post a description, how I can do the parameter-linking in Reaper? Maybe with some day to day-examples how you use them?
I might add such parameter-functions to my Ultraschall-API to make things more comfortable, rather than having to deal with the StateChunks, but I still need an practical use-case-angle on how to approach that...

I was chunked it hardly with a bit of reverse engeneering (long time before mespotine`s docs has arrived).

All I can do is to quote Justin I agree with: "Try to avoid chunking". So good luck with it.

Thanks Mespotine. I will have a look at your docs!

The typical use case here for me is having several instances of the same fx on a track (let's say 3 reverbs) and then linking all of the parameters to the first fx instance's controls (with small adjustments to them) so that when I touch the mix parameter in fx1 then the same parameter changes in fx 3, etc.
