I hope this is something obvious... do I have to log in online to use my Amplifi? I get that I would not be able to use the cloud features offline, but it would seem obvious to let me program my app tones without having to be logged into Line6. Also, if it's not there (haven't found it) the app should save your login credentials and default them when you open. It seems to clear them every open/close of the app. I have not spent a ton of time with it, so this may be operator error.
Also - PLEASE add a PC/Mac application with USB connectivity at some point. The iPad app works well, but hardware updates and os updates are too frequent (also, some people would prefer Android, etc.). To be a serious tool, I think you need to have a computer based application to fall back on as well.
Otherwise, I really am enjoying my Amplifi 75.
