Excellent, I did try to find some Trumpet calls for the cavalry but have had no luck (interestingly, according to my book on Civil War drumming, dragoons had drummers). By the way, I have just Pm'd you some more background music suggestions.
So Should I make dragoon drummer or infantry drummer is enough?
I would just stick with infantry for now. Of course they would be mounted and ride in but I don't know if they had a different type of drum, I will look into it. Oh and good to see the footwear issue is fixed!
And in reply to Augy, I did suggest having the option to be a Leveller, a Puritan priest, a Catholic priest and an Anglican priest. Perhaps it would be good as well to have the option to be a camp follower. Women regularly accompanied the armies and would most likely tend to the wounded (although it was very rudimentary and most likely after the fighting had stopped). Infamously, the Parliamentarians massacred dozens of Royalist woman after Naseby because they thought they were Irish Catholics (they were actually Welsh). Still, these things are complicated so it will take time.
EDIT: Just found this over at Warlord Games:
It would appear then that drummers in the dragoon regiments looked exactly like an other drummer (being cavalry some are wearing boots)but would sling their drum across their back when riding into battle. When they dismounted they would then beat out the calls.
