Oh ! Excellent !
I have some knowledge of music theory but I am not familiar with orchestral/filmic music.
I didn't know you could make it sound so good with a mode change. So if I understand correctly, you alternate between Lydian C and Aeolian C. That's great! I'm going to have a blast on my piano to discover these new possibilities. Thanks a lot.
Ps: which sound bank do you use?
