Geoshred distorted sound with garage band

I have been learning geoshred since few months. When I stepped for recording geoshred on my I pad air using garage band with other synth and beat sequencers, happened to be easy, and sounds good but after exporting the project or as a song geoshred is completely distorted , melody is gone ,no pitch blends , totally odd to hear.

Please anybody suggest a way to record geoshred.
