[Solved] custom midi notes

Hi, I use Sonar X1 LE for recording and here is my problem. I want to add midi(not sure if it's the correct word) bass to my recordings instead of playing real bass. So I insert soft synth, choose Cakewalk Sound Center, and select one of the bass tones. Then I press "alt+3" and write notes in Piano Roll at the bottom menu. There is no problem so far. But I can't select custom notes, for example I want to have sustain in one note and make it go for 2 bars. I can't; it goes only 1 bar as I can only select a whole note, no other option it seems. Is there a way to do this?

Thanks, actually I guessed and tried that myself before in "draw" mode with no success and was gonna reply to you but I tried it in "smart" mode right now and it works, I must be stupid not to figure it out.  :)

ok thanks, solved  :)
