M=sawtooth_fract32_module(NAME, SR, BLOCKSIZE) Creates a sawtooth generator for use in the Audio Weaver. This module has a single 1 channel output pin with controllable frequency. The output of the module changes instantly when the frequency is updated. Arguments: NAME - name of the module. SR - sample rate BLOCKSIZE - number of samples per output channel.
