no

So if I purchase a Sonar Home studio I can find the Studio Instrument Suite with no limitations inside?

Ok, thank you very much. ps- I read that Sonar Home Studio includes 700 loops. So that means that it contains a drum machine to write drum parts and loops?

SI Drums has over 30 kit programs, as well as patterns in many styles, such as Electronic & Pop, Hip Hop, Jazz & Blues, Rock, Soul & Funk.
 
Any of these patterns can be dragged into a MIDI track as a MIDI clip for editing with the Piano Roll editor.   The MIDI clip can also be converted to a step sequence and edited in the Step Sequencer.
 
You can use these drum parts and loops you edit or write from scratch to trigger SI Drums, or any other drum instrument you may have.
 
The other SI instruments offer similar functionality with MIDI patterns.

Ok. So, i think I will purchase Home Studio to have unlimited midi tracks + SI instruments with no limitations. Thank you very much to all for the patience you had

SONAR Home Studio allows a maximum of 128 MIDI tracks. Unlimited track count starts with SONAR Artist. See limits here http://www.cakewalk.com/Documentation?product=SONAR&language=3&help=Comparison.html
