This looks like a forum for comments and questions about musicians using Audacity, but in the header it says "for help, post in your OS forum "( Windows ). Is either ok?
I’m going to ask about settings to record from my Line 6 Helix, while at the same time, monitoring a backing track from Audacity ( usually results in glitches and/or changed pitch on the recorded track )
Questions about using Audacity are generally best on the appropriate “OS” board. The sound system on Windows is quite different from Mac or Linux, so you need an answer that is specific to Windows.
