Yes, Lame Duck is a good descriptor. This excuse of not what it was designed for is pitiful. The whole benefit of software based tone controls, amps, guitars, music instruments, etc - is that they are always being improved, constant innovation. That's what a true successful platform does. Otherwise, just buy a 1969 Fender amp and be done with it for 50 years. At least you know it will work reliably.
Response to issues on the forums is the most pathetic I've ever seen (my day job is software, so I can tell you this is amateur hour here). In a day and age when the world is more and more dependent on software development, these guys are obviously hiring dregs of the universe in both software development, product support and company management.
No inspiration here to buy anything from Line 6 every again.
