I'm lost because two expert users (thanks both) give opposite answers :

A positive answer from TheRealZAp (many thanks again):

"as long as you paid for your pod farm 2 license (meaning it wasn't included with a line6 hardware purchase)

pod farm 2.5x + and the model packs will all be hardware independent.... (*assumes that you also paid for the model packs)"

A different answer from Triryche (many thanks too):

http://line6.com/support/message/365934#365934

"Model Packs are only compatible with certain Line6 hardware, never for i-Lok. They are currently not compatible with POD Farm for computer (non i-Lok).

(Unless you previously owned a purchased model pack from a compatible Line6 Hardware device, then purchased POD Farm 2.5 Hardware independent.)"

In other words : for pod farm 2 and model packs, do we need any Line6 hardware device as dongle or not ?

(maybe you're both right but if that's the case, it means that my level of comprehension is too low - english as a foreign language is not so easy )

My doubt is about Triryche last sentence : "They (model packs) are not compatible with pod farm for computer".
