I FOUND OUT how to add send tracks all by myself, but if anyonw wonders about it heres the answer:
In pattern view or in mixer view, CTRL t = add track.
if your marker is somewhere on the left side of the master track a new track will be added.
If the marker is on the right side of the master track, a send track is added.
Also right clicking either on the left or right side and click insert track in the context menu will do the same.
It only took me a few hours to figure this out! I thought it would be good to have this info somewhere to save other newbies from wasting huge bulks of their lives!!!
