I’ve searched pretty extensively and come to the conclusion that it’s not possible to play along with YouTube or Apple Music using the Irig. The levels are not adjustable separately. I’m curious if anyone has figured out a work around or uses another app? I would like to increase the guitar volume without distorting the signal. Otherwise I think the technology is fantastic, getting some really good tones. I travel a lot so I use it to jam in hotel rooms and what not.
