It's 100% inexcusable that Line 6 still has not enabled this feature for PC users. My phone is a phone, I don't want to connect it to my amp. Also that totally defeats the purpose of using the USB output to record.
Two years since this request first came out as well as the request to add to0nes to the PC editor instead of only the crappy phone app, no response from Line 6. Fair to say they don't give a crap about the Spider?
