I recently purchased an alesis dm5 and 2 ddrum redshot bass drum triggers, my questions are how do i set everything up? i bought the dm5 used so it didnt come with the manual so I have no idea on how to change the sounds or change the sensitivity and how to get the same sound for both bass drums, and also how do i mount the ddrum triggers on the bass drums? if possible can someone show me a link to video or something explaining how to set everything up? thanks in advance for the help
