What is the limit for automation parameter in VST spec?

Hi, i can't find a answer to my question. Does anybody know how many parameter are the max supported limit?

128?

 

Or is this host specific?

 

Thanks,

Tommy

I've seen plugins with hundreds of them, but having that many just makes it impractical for users to make sense of what they all do.

Yes, it's true.

So there is no limit set by any spec?

 

Cheers.
