Overview
Counter module with optional wrap around
Discussion
This module counts up starting from 0 at a specified rate in milliseconds. The count value is output as an integer value on the output pin. The module has an input pin whose only purpose is to get the current sample rate and blockSize. This information is used to determine the time base for the processing. The sample rate of the output pin equals the sample rate of the input divided by the input block size.
...
When muted the module outputs all zeros. When bypassed the module continues to run.
