I should probably have mentioned that when you insert a continuous controller command into a song, it will be inserted wherever you click in the numeric grid.

If you mess up and put a patch change in the wrong place, you can fix it in the event list (F2 opens the event list in Real Band)

But the easiest way to place the event at the right place is, after you select the type of CC you want to add, and you are ready to click in the numeric grid at the bottom of the piano roll screen, place your cursor at the measure and beat where you want the change to occur before you click the number (cursor will show as an arrow, and will clearly show where you are about to insert the CC)

Remember its a grid (horizontal and vertical location)

The vertical plane is where your number is picked, and the horizontal plane is where the timing/placement is determined. The CC is actually inserted at the horizontal location in the song where you click the numeric value.

Sorry for all the detail... some people require it, some don't. Better to have it and not need it than to need it and not have it.
