 To distinguish them from normal monophonic cables, polyphonic cables appear thicker and can contain any number of channels from 2 to 16.
 
 Without polyphonic cables, patching a polyphonic synth would be very cumbersome, with increasing difficulty the more voices you need to support.

 But with polyphonic cables, you only need to patch one set of modules and then configure a single "source" module to generate a polyphonic output.
