Manual state that Morph is to be midi CC#3.
You could see at midi monitor in StudioOne whether this arrives or not.
If arrives and not recorded see if any setting for a filter that I think is there. CC#3 is not that common.
Just beware of how StudioOne handles continuous midi CC. I abandoned StudioOne because of it. Don't know if fixed in V5 though.
What happend in V4 was that all incoming CC is converted to automation.
And lets say you a couple of bars into a recorded clip start moving a knob like Morph.
Then this first value that is sent is made the initial value of the recorded clip, which might be or not what you want.
The value is not sent where it first occured. It is sent as initial value at beginning of clip, or you have to edit to modify to zero if knob was all on A as start.
Most daws allow to convert to automation or not, V4 StudioOne did not give a choice.
I had issues with this with many things like leslie on/off for hammond etc. Since on/off thingy the first value was On, since you sent that sometimes while playing. So leslie was always turned on if used in a clip.
Just a remark to check out so you get what you expect.
