Motif 6 c4 key opens save as in cubase

My midi keyboard motif 6 keys does things in cubase. Like change the time line from bars to samples or time. Brings up save as. Anyone else have this issue?

Hi and welcome,

Open Devices > Device Setup. On the left side you can see Remote Devices folder. If there is a Generice Remote Device in the folder or Mackie Control, make sure, there is no MIDI Input port (it’s set to Not Connected).

For some reason your Motif is handled as Remote Device, which control Cubase, I would guess.
