IA suits the hard rock songs that Jin writes more than Miku........... he could have used Gumi or Rin for his songs to get similar if not superior results. Nemu tried IA and probably came to the conclusion that he's better off sticking to Gumi.

And the flat high notes is more an IA issue than an issue with Jin's tuning.
