I uppgraded my Cubase from 6.5 to 8 about a week ago and I’ve been trying to set up my music system again after 1-2 years break and trying to learn to use it. Many problems solved, but couple of show stoppers still left. When I enter notes from Motif XF8, I hear the right sound from Cubase, but keyboard also activates some key commands. For example when I press C2, Cubase opens save as-window etc. Another problem is that for example when I select one track Cubase plays a certain sound and when I select another track Cubase plays another sound. Not needing these sounds. Any help would be appreciated.
