Note input issue with digital keyboard
So I've set up my digital keyboard and can input all notes from my keyboard - all except the C# just above middle C. This is not an issue with my keyboard as I am able to use all notes without an issue in Synthesia.
However, what I did discover is that, during playback of my composition, I can press any key and the sound will play on top of the playback, but when I hit the C# it comes up with "Command pad-note-4 not valid in current state." Does this mean that the note is assigned to some command I am unaware of? If so how may I change this? Thanks!
