Editing Controllers In Cubase Sl, newbie question Options

[nick d]

Hi all, a couple of things that are not clear to me. First, I want to select a group of controller events, cc #11 for example, and increase or decrease the relative values by the same amount. In my other seqencer this was accomplished by selecting the events, and then click/dragging up/dwn in the value field. So far I am only able to change one event at a time in sl, except for velocity in the key editor, where I am able to change as many as I want at once. What am I missing? Second, what is the best way to thin existing controllers in sl? I have read the manuals, and am still unclear. Thanks for your help.
