I noticed a while back that my drummer app - Soft Drummer, displays the icon for AUM when i've opened SD (and GTL) inside
AUM. Tapping on the AUM icon then bring it up.
Having such a feature in GTL would be handy. Currently one can switch to GTL if one is also using AudioBus - by bringing up the pull-out-toolbar thing. Or one can just launch AUM the old fashioned iPad ways. But having this icon just included inside GTL when being used would be really handy.
So much brain-power gets expended on switching between apps - in order to view them or adjust volumes, stop-start transport etc - so any thing that makes my minuscule brain able to focus more on the music-side the better
Oh and - Did i forget to mention... I LOOOOOV THIS APP !!
