The Audio Switch Box is a bit more modern looking but it does exactly the same thing as my switch.

Due to the fact the headphones work well with both devices there are no impedance issues.

To go from one device to the other requires a switch. That switch could be as simple as unplugging and plugin in the headset...that is what you have been doing and controlling the volume with the device.

To listen to both devices at the same time requires a mixer. of some sort.

What is the Ipad software you are using? It would be fun to take a look at.

I tend to play in key for the most part and have a pretty developed sense of what effect certain chords will have. The demos in BIAB in various styles will give you many good ideas about chord progressions.
