I can make midi automation in midi track. But how make automation in instrument track? The midi is not in automation list.
 
And how can i change or add clip name? For midi or audio.

If you want MIDI automation exactly like a MIDI track, you would need to split the instrument track. If you want to keep the instrument track, do the MIDI automation in the Piano Roll View.
 
Clip names can be changed in the Clip view in the inspector.

Thanks.
But what if i have midi automation and now i decide transform midi track to instrument rack and edit automation in instrument rack? If i do it, my midi automation in pianoroll is empty and i must have split instrument track again. I cant understand why instrument rack dont have midi automation.

Some of the features of MIDI and audio tracks are not available in simple instrument tracks. It was a design decision. You can send in a feature request for whatever your like but for now you have to decide which is more important, using instrument tracks or using the features provided in the MIDI+Audio tracks.

I see absolutely no reason to use Simple Instrument Tracks over split Midi + Audio.
 
The only thing you lose - in my opinion - is that you have an additional track on your screen, but the effect of this can be totally mitigated by using Track Folders and setting up different Screensets
