+1) Problems with feedback were mitigated by brining down the input gain.
+   In generate the input/output gain were set to:
+      In Gain:  0.7 0.2
+      Out Gain: 2.0 2.0
+2) Turning the piano away from the microphones also reduced feedback; probably
+   due to the fact that the piano lid sheilds the mic's from direct path
+   from the speakers.
+3) Increasing the threshold and and use of mode 4 (Bump Mode) produced the
+   best transformations.  See Preset G in mod_44_45.js
+4) Input signal conditioning needs to be added to keep the piano signal 
+   in the effective range of the transform.
+5) The Sine Tracking feedback controller is in an uncertain state.
+    a. The attenThresh setting range needs to be verified.
+    b. The scoring function was changed and then not verified.
+    c. The algorithm which compares the trajectory of a given harmonic
+    to the trajectory of the overall sound needs to be writen.  
+    Harmonics that are increasing relative the overall envelope
+    should be attenuated.
+6) A noise gate might help the reberberation feedback problem (i.e.
+   the dense wash of sound with tends to build with time)
+7) The transform algorithm needs to be developed further to increase
+   it's reliability and range of effect.
+8) Changing window length from the score didn't seem to be working.

 0) Investigate using omni mic. in front of speakers to feed input to cmFrqTrk.
 1) Feedback from Mark 178, m144, Preset C.
