Basic Assembly and Setup

I have the NyBoard V2. I am able to compile and upload the testBuzzer module. It makes sounds, but the beeps sound more like alarm buzzers and the meow sounds like an electronic screech. Any tips on how to adjust these sounds?

I tried the WriteInstinct module (and set the version in Instict.h to "#define NyBoard_V0_2"), but got the same result.
