Delete channel node

Removes channels coming from its input.

The Delete chop removes channels coming from its input. The channels are selected by a variety of methods, which may be layered. The first method uses a text string to select channels by name or index. The second method uses a value range to select channels with samples within or outside the range. The third method selects constant-valued channels.

An option selects whether to delete or output the selected channels.
