Looking forward to upgrading, but I already have Addictive Drums.  For us forward thinkers, is a discount possible?
 

No, but if you contact XLN, they may offer you something.  There was a thread on here where it was mentioned they may give you an adpak or something.

This is the post http://forum.cakewalk.com/FindPost/2909415

I just did this.  They were quick to reply, and said I could supply the Serial Number for AD that came with X3 in exchange for either the Retro ADpak, any two other adpaks, or the Studio Addictive Keys.  Awesome!!

That is a nice gesture.   Although I've been somewhat "anti-XLN" for the last year due to their online only process, having AD and AK on my system now by way of X3 and now seeing this type of thing has started changing my outlook. 
 

Very cool! I'm new to AD, but I'm impressed with the interface, options and sounds.

Thanks for the info!
 

Very cool of XLNAudio to put this offer out there.  I already had AD, so the one bundled with X3 wasn't doing me any good.  I emailed them last night about it, and this morning found the Vintage Dry ADPak and Electric Grand added to my account (I own most of their other products, and these were the two I had on my wish list).
 
Thank you, XLNAudio!

That's very cool of them!
