v1.1.2

• fixes a bug where after 16 audio patterns were played with "keep()", voice handling did not work correctly.
• fixes the turing() generator method so its output is between 0 and 1. The noise() method was updated to a bipolar range prior to v1.0, and this method relies internally on noise() but was never updated to keep the data scaled to the proper range for a turing sequence (0-1).
