Press space to start the 1 ,2 ,3 ,4 and 5, and click the 4 pad to ring it (I will do it for other bells too) Press a for a call change (randomised). To get the others moving to the right place, press: 1 for 4 to 2 2 for 2 lead (<- this one doesn't affect you) 3 for 3 to treble I hope you enjoy this and comment below if you find problems.
I made this with my call changes skill and timing skills. This is aimed for beginner bell ringers (like myself).
