Overview
Source buffer holding 1 wire of data
Discussion
The Boolean source module has an internal buffer holding 1 output wire's worth of data. The module continuously copies the data from the internal value buffer to the output wire. Since this is a source module, you must specify the number of channels, blockSize, and sample rate of the output pin.
Type Definition

M=boolean_source_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE)
Creates a source module that allows you to inject Boolean data into the audio
processing layout. Arguments:
NAME - name of the module.
NUMCHANNELS - number of interleaved channels in each output pin.
By default, NUMCHANNELS=1;
BLOCKSIZE - number of samples per output channel. By default,
BLOCKSIZE=32.
SAMPLERATE - sample rate of the output signal in Hz. By default,
SAMPLERATE=48000.
