Yamaha Key Commands???

Hi Cubase guys.
OK, I have a UR22 (lucky me :slight_smile:) a Yamaha DGX keyboard (I use as a controller as well) and of course a PC. I am using Cubase AI8 (?) Anyway, it has function brilliantly since I installed it about 6 months ago until today, I dont know if I have accidently clicked on something, but earlier, I opened up a VSTi the halion synth and I didnt want to record stuff as yet but when I played the note ‘B’ it triggered the record function, and when I played another key, a save window opened, whats happening? Please help!!!
Thanks guys :slight_smile:
