The Mellotron Group

While listening to a live version of the Moodies' "Have You Heard/The Voyage" yesterday, I began wondering about the logistics of changing settings on a MkII while in the middle of a song. Pinder uses 3 sounds: Church Organ, Flute and 3 Violins. He uses Church Organ in the beginning, then changes to Flute for the verses. In the beginning of "The Voyage", he goes back to Church Organ and then changes to 3 Violins. When Pt 2 of "Have You Heard" begins, he uses Church Organ and Flute again. I'm assuming he kept one keyboard on Church Organ and switches the other keyboard between Flute and 3 Violins. Flute is on Station 1, Track A and 3 Violins is on Station 2, Track A. Anyone know how long it takes to change stations and have the keyboard become active again after pressing the station button? How does the time compare to an M4000?
