It seems to be slightly bizarre but there is no editing of any control messages, eg pitch bend, modulation, etc. Even more bizarrely is that if you move or copy a track, the control info is not moved with it and therefore either goes out of sync or is missing, depending on what you are doing. And if you then record something without (eg) pitch bend into somewhere where it was, it is still there, somehow deatched from its original track! This needs to be all sorted out soon - but i am sure that Steinberg are aware of this.
