Logic Pro X Midi Mapping

Thanks mate. That's a solution, though a better option is to use producer kits. However, it is not intuitive. So what you do is apply the producer kit and then in the mixer you will find a little arrow at the bottom of the channel strip. Click on it and voila, it opens up the (sub)mix to the kit.

That would change the very character of the sound rather than the level. Surely there has to be some other way of achieving this. To borrow from live recording, when all the parts of the drum kit are mic-ed up, we can turn the level down on individual bits of the drum without impacting the character of the sound.
