+1-synth_sine_f32.h & .cpp allowed both KINETISK and__IMXRT1062__ to support T4.x.  Tested 3.6, 4.0
+2-Hid synth_pinknoise_f32.h & .cpp with .xxx type.  Allows T4 compile until these are fixed.
 
 **Purpose**: The purpose of this library is to build upon the [Teensy Audio Library](http://www.pjrc.com/teensy/td_libs_Audio.html) to enable new functionality for real-time audio processing.
 
-**Approach**: I am attempting to follow the structure and approach of the Teensy Audio Library so that coding techniques, style, and structure that works for the Teensy Audio Library will also work with my library.

 **Send Help!**:  While I'm hoping to follow the pattern of the Teensy Audio Library, I am not a well trained programmer, so I have difficulty chosing the right path.  If you see ways to make my code better aligned with the Teensy Audio Library, send a pull request!
