This video is so small and dark it's difficult to make out the settings. Can you provide more detailed instructions including the settings and actual notes?And how about doing this for some other classic Mellotron tracks like Watcher of the Skys by Genesis or King Crimson's In the Court of the Crimson King?
I would recommend downloading the guitar tab for Strawberry Fields, working out what the notes are, and programming it in yourself - you'll learn so much. At the same time, take a look at some of the Mellotron videos on YouTube of people playing these songs you are interested in, and just work it out. You'll have a great time trying.
