I got nothing here either. I logged on to the addictive account and looked. I found nothing.
When I purchased X3 I downloaded the addictive drums and quickly set the account up. I have been using addictive drums on a few projects but I never went back to the AD web site to look around.
When I seen this post I logged in and started to look for the third party stuff and I found nothing. I started searching around to see if there was anything else that could be offered for free from this site.
I found a Pop Rock add on pack for free and a Funky Groves add on pack for free. I also found an additional bass drum called DW woofer. This is a monster kick drum. I like it.
When I clicked on the add on packs to download an error came up that said I could not add this to my account because AD did not have my zip code or mailing address. When I setup my account with AD I only provided an email address.
I went into my account at AD and added all the missing information except my phone number. Those free add on midi packs immediately became available. I downloaded those as well as the free Studio Grand Piano.
I am not sure but maybe the reason I can not see the third party plugs was because my account was not completely filled out. Maybe somebody can clarify this.
I will check back in a day or two to see if nectar is available. There is no Third Party Products category available in my account. I did scroll all the way down.
