Hey, sorry for the delay on responding to this, and thanks for asking about xformer. xformer is a strange module, and I agree it’s not well documented – neither in the official documentation, nor within our internal notes. We are actively doing R&D for a newer, more suitable module to accomplish transformer-style saturation with clearer documentation/controls/sonic output, though I can’t comment on when that might be released to the public. There aren’t any sigfiles you can view which use the xformer module.
For the time being, I recommend you keep area set constant to 1 and saturation set to -1. Then n1 becomes the number of primary turns (lower turns = the system saturates quicker, and the volume increases) and ratio can be used to match the output level (higher ratio = louder output).
A quick technical note: xformer is only valid for a sample rate of 48k. Weird things can happen when you move off of 48k. We are actively working to fix this.
