I can't play any sound with virtual instruments

[escapeplan4]

I've got free version6 previous was 5 and it worked fine but I switch to 6 and I don't have any sound from it. I only have laptop no keyboard or anything and I just want to play from asdfghjkl ( means laptop keyboard) I add midi device in settings and attach it on track but no sound even when I chose a sound from bank. It says "this track contains midi generated clips which might be inaudiable as it doesn't output to midi device or plugin synthesiser. To change a track's desttination select track and use it's destinations list
