Hey Gary - NAM (neural amp modeler) is a project that was started by Steve Atkinson around about 2019 or so..., but in the last 3 years it's become quite a big community which I've had the privilege of helping manage alongside Steve and since then independently of Steve's project, a few people myself included, started Tone3000 (formerly Tonehunt) which has become a website for uploading / sharing and more recently training NAM models in the cloud via remote GPUs. I help out across the board - so if you need any more information you are welcome to ask and there's a dedicated thread on this forum too where I'm sure anyone will be happy to help.
If you are on facebook, there's an official NAM community, and there is also a discord server for Tone3000.
Let me know if you'd like links to those.
As it's open source, lots of people are building out from both the training and the playback and processing perspective, so there are now almost countless products for windows, apple (mac and ipad), linux, and hardware.
Anyway, I'll leave it there, but in the context of this thread - I would love to see Line 6 Stadium offering some form of NAM support, be that natively or conversion to their Proxy format.
