I'm using Amplitube CS and Garageband on iPhone 7. But I have a problem. I can listen my songs which are created with Amplitube ( using Inter-App Audio on Garageband). However, when I shared my song with others, people just can listen sections which are created with Garageband. Sections which are recorded from Amplitube with Inter-App Audio on Garageband haven't got sound. But I can listen all sections in my phone.

Edit: I found something. I can share my clean sounds but I can't share distorted sounds. Do you have any idea?
Edit2: I solved my problem. I'm using direct box in Garageband and I can record and share my songs.
