I have a question about dual lightning port and data transfer.
I am now using camera module to connect iPhone and portable keyboard which sends midi signal to GarageBand. But thanks to apple’s policy of having only one port with their product, and large latency of bluetooth earphones, I can get keyboard(via camera module, which has female USB port for keyboard and male lightning port) working properly, but cannot be delivered with audio output!
I tried only one product until now to be frank, and it did not provide me with data transfer but only power supply and audio output, so I couldn’t connect both keyboard and my EarPods.
There is a promising option to use external audio interface whose connection is done with USB cable connected to USB Hub. But is there any also promising dual lightning port which ensures both data transfer of MIDI signal and audio output?
