включаются все нажатые ноты и не выключаются

Check event view for orphaned sustain pedal events.

The OP translates to: 
 
"included all held notes and do not switch off"

в sоnar x2 все нормально, проблема в sonar x3

So, same project (identical with no edits), behaves differently between X2 and X3?
It could still be a "stuck" sustain pedal event, that X3 is respecting, but X2 did not (because of a bug or something).
 
So, I recommend checking your project.
 
What happens if you direct the MIDI track to a different VST instrument? Same behavior, or only this specific VSTi?
 
Can you upgrade the VSTi to the latest version (this may not be possible - It seems YT Majestic seems to have vanished...)

все остальные инструменты работают нормально и только  majestic глючит

It is probably a defect in Majestic, then. Good Luck!
