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.Â
