AJ I think you are the only person who can give me an answer about my question below because I have try this before but no one reply

I must ask this question again because I have never got any good answer on it, maybe AJ can give me an answer. Say for ex. I have a midifile in C maj. and have transposed it 2 step D maj and I have also on channel 4 set the vocal to midimode and the keyboard is also transposed 2 step so I can play in C maj. than in the midifile I have a transpose before the last vers, I will continue to play in C maj so I transpose only the keyboard 1 step and so far itīs good but my question is, why is the vocalizer affected when I transpose the keyboard, the vocalizer is still in midimode and nothing else in the midifile is affected?
