For those of you who either have an Abbey Roads Drums software like Abbey Roads Modern Drums, or have one of the Komplete packages that comes with any of the Abbey Roads Drums software, You should have received an email a little while ago allowing you to upgrade to the new Abbey Roads Drummer software that relates to your Abbey Roads Drums software. Like if you have Abbey Roads Modern Drums, you get a free download for the new Abbey roads Modern Drummer software.
I saw a YouTube video that explained the new software, and that owners of the ealier software get the upgrade for free. So I went through my old email and found my serial numbers and download links. Check your email!
