How to change tempo in just one track I chose, among all tracks in my project?
not posible -you need to manually alter the note length / spacing in the specific track.
BMP is for the whole project
(read up on BMP pecularities when using imported midi's -search here or read the wiki)

I see, thank you for help. Anyway maybe you know, if it is possible to request to LMMS developers group to add such option in future, which will make possible to change tempo speed in a specific track(or in a little part of track, like it is made in Presonus Studio One Free, option of tempo changing in a specific track or part of track makes work much easier)? And also to add driver ASIO to LMMS? Because many people need it. My father composing music, and he likes the CUBASE, and i try to start work on LMMS, but he was so disappointed, because he got delayed sound from real time play on keyboard during recording to LMMS.
You can post wishes for features you miss here:

Thank you very much
You either have to manually drag the notes on that track longer, or you could mute that track and export the rest of the song. Then export "that" track and none of the others, and then use e.g. Audacity to make "that" track longer and stitch it to the rest.
