Each of those styles has hundreds of drum tracks. Did you find something specific that you thought was in a gallop pattern?
Will,
I entered the song you mentioned: "Running up that Hill" in the StylePicker, and the Styles that were recommended were provided.
I listened to the Pre-made Demo samples from several, including _ACFNK16 which I felt potentially had a rhythm similar to what you described (at least my interpretation of 'galloping drum pattern').
But I don't understand what you mean by 'Each of those styles has hundreds of drum tracks'. Each style only has one drum track, or have I missed your point completely? Appreciate your clarification.
