oh, i guess first generation is ok then, infinite encoders sound not too useful for analog recording indeed.
i once had one of the first line6 usb interfaces and that was glorious!! i could record my signal dry but listen to it fully processed during recording. and that was years ago, like 10 years or so.
i could never believe that focusrite had not achieved the same, so i was frustrated when i found out o could only record metal guitars dry. what a not rocky way to get into the vibe of heavy music ahaha.
we have 12 volt electricity in the car and use 5v transformer outlets. no inverters to 220/110 v
guess i found a real tech nerd, awesome. i may have questions in the future and will seek your advice if you don't mind.
edit: that was the first toneport ux2 i believe, by line6
