Ok, I see Steve implemented NAM import in some of the latest versions so you can now also open a NAM file instead of checkpoint file. So you could download a NAM file from https://www.tone3000.com/ and use it as starting point for your own capture I guess. Wonder how much time that would save and what would the results be when compared to full training using you own data set...Yes - you can use checkpoint-based training to resume training from a given checkpoint allowing for such tweaks. It's a bit niche but can be done.
