Midi sound issue!

Hey! I have such a problem: I added a new instrument track, loaded Kontakt 5 and some clap library. Everything was fine but later a noticed that this track has no sound. On uploaded file you can sea that my DAW see incoming MIDI and shows loud but it is silence in my speakers. Other instruments have the same problem but the rest are fine. How can I fix it?

I am presuming that you have checked the routing of Kontakt’s output channel.

I have occasionally had this problem, which was only solved by creating another version of Kontakt. Kontakt does not always play nice with Cubase. Make sure that you have the latest version of Kontakt. If this isn’t the case a little more info about your system might be helpful.
