Hi 
Is it possible to remove note titles in piano roll notes?
(not sure what you find annoying about them 
, but anyways)…
a) The note names only appear above a certain vertical zoom level
b) If you activate “Show Note Expression Data” in the extended toolbar, the note names disappear.
c) You can also choose (to a limited extent) how the note names will be represented, in Preferences>Event Display>MIDI>“Note Name Style” (but that affects Cubase globally, not just in the Key Editor).
Second proposition is most likely what I need. The only problem is notes change their look (colors and borders). But if there is no other way to hide note titles then this one will do. Thanks
