Hi, we’ve recently bought our son a legacy dd505 second hand as a starter kit. Everything works fine apart from the hi-hat controller which he has to really stomp on to get the closed sound. He’s only a little lad and is finding this really difficult. I’ve adjusted the sensitivity of the controller as per manufacturers instructions but it hasn’t helped. Any other ideas? For now I’ve changed the hi-hat sound on the brain module so it is always closed, but that’s not a long term solution! Thanks for your help - total drum novice here and feeling very much out my depth!
