How do I record through the headphone jack?
I want to record an external synth in Garage Band through the iPad headphone jack. I have a 3.5 mm male to male 35 mm cable running out of the synth into the iPad, but it won't record any audio. The garage band audio recorder and sampler only seem to work with the built in mic, and the guitar am recorder doesn't pick up any sound. Anybody know hiw I can accomplish this?
