parameters[].is_automated questions

I have some questions regarding this note in the Renoise Song API doc:

-- Is automated. Not valid for parameters of instrument 
devices.renoise.song().tracks[].devices[].parameters[].is_automated, _observable
 -> [read-only, boolean]
  • Will be is_automated true as soon the parameter was automated somewhere in the song, even if that automation symbol is greyed out (no automation on the current pattern) ?

  • What does “Not valid for parameters of instrument” exactly mean? Is it not working on the Instr. Automation Device?

Ok tried it, FYI:

  1. It is true also for greyed out

  2. It works also for the instr. automation device

What does “Not valid for parameters of instrument” exactly mean?

It means that automation is not valid (i.e. does not exist) for parameters within an instrument’s device chain.
