I know not whether this is meant to be or not, but it confuses me a bit.
In the GP file, the key is "E major", however, wouldn't that suggest that the lydian mode should be A lydian? Where as E lydian is a part or the B major key? Same goes for the change to Bb lydian, which is in the key of F major, where as the lydian mode of the stated Bb major key would be Eb lydian?
Could you explain this to me?
