I used sonar now about six years, i bought myself a special keyboard, but it is the last time i ever use it.
It is a great programm if it works, but it gives always troubles.
I have tride several computers at home, and all have the same trouble.
They have to fix the scroll piano view, now i have the x2 same problem, but more.
And then you spend hours to make a midi file and you have open the scroll view and the system goes fault.
All your work is gone, because you can open it again.
What i say, it could be a great programm, but they cant fix it x1 and x2 both the same.
So i say good bye i go to fruity loops or cubase
