Total Bundle 3 here. work in Sonar 64bit for me with no problems through bitbridge.
as other have stated I don't use them much, long in the tooth. Amplitube 3 is nice.
I mostly use Miroslav Philharmonik.
I hate the customeshop with t-racks and amplitube. I have never purchased additional stuff frorm the customeshops and won't.
I was lucky someone bought this for me as an Xmas present so I didn't actually purchase, though I own it. If I had spent my money on it I would have been rather upset and disapointed.
If you don't own NI Komplete I would invest in that before buying the IK products. as I have both it's nice to have some extra products from the Total Bundle if I need them but rarely use them.
