The iPad input wouldn't handle stereo as it's a single mic only. Stereo headphone and mono mic.
You may also have an issue with the mic input being too sensitive for the keyboard output.

Something I just learned whilst checking things is that the pin wiring varies depending up the standard used, apparently left and right headphone outputs are constant, but mic and ground on R2 and sleeve may reverse. That's likely OK for a mic, but with keyboard to iPad that swap may also cause issues.
