The piano solos were recorded separately and pasted in the overall project without much success, I'm sorry for this.
Thanks to Stephan Brandel for the collaboration.

Aria MKII Flute

Bad sound quality, haven't managed yet to get Aria's piano sound correct via midi. Any idea what's going wrong? (OS X El Capitan 10.11.1)
