To mix music or any other auxiliary signal, iRig HD2 obviously needs an app (like AmpliTube or GarageBand) to accomplish this.
Audio signal from a browser (music lessons for instance) seem to be output on HD2’s phone jack, an instrument connected to HD2 however will not be mixed in.
Is there any way to accomplish this or any other interface that would provide this capability?
Goal is to play along with online music lessons or YouTube videos.
Thank you!
