to my knowledge Stamp is correct .... no stop command
do a button pause macro if you want .... raise command will be sent until you release the button.
if you use different equipment, that needed a stop, you could put the stop after the button pause.
I prefer using scenes and preset amounts for most clients though.
Peace - It does not mean to be in a place where there is no noise, trouble or hard work. It means to be in the midst of those things and still be calm in your heart.
