Overview
Multichannel mute module
Discussion
Multichannel smoothly varying mute module. The array .isMuted has a separate value for each channel in the signal. The size of .isMuted is set by the prebuild function. You can also separately specify the initial length of the array using the optional second argument to the function. In all cases, the array length is updated by the prebuild function.
...
By default, the inspector for the module has the control checkboxes organized in a vertical stack. By setting the optional third argument TRANSPOSE = 1 turns the control into a horizontal stack.
