I can not find the draw function for studio one 4 midi editor

Hello Studio one Team

My name is Michael, and i recently downloaded your product from your download page. I started it up to check out its functions when I realized that I can not draw individual notes in the MIDI editor for studio one 4. I looked up some tutorials on how to edit and draw notes in studio one 4, and it showed that the draw function should be at the top of the editor bar but when I checked once more it was not there. Can anyone lead me to where it is? 

here is a screenshot of what I see: 

With all due respect, thank you for your time, is you see this. 

Michael
