Switch the audio input between the 16 outputs by sending a MIDI program change or choosing the output in the GUI. Each output has a processing mode parameter that you can see in the Parameters dialog and link to another bidule or group of bidules processing mode parameter. When the output is selected the parameter is set at "Processing" and when it is de-selected it is set at "Mute". With this it is possible to have complex layouts and having only the wanted bidules using the processing power.
8/16/32 ins/ 8/16/32 outs device with a grid to select the routing. Left of the grid is the outputs and top of the grid is the inputs. The Close MIDI Notes option will automatically close any opened MIDI Notes when turning off a cell.
Same principle as the switchers except that the added MIDI port is use as the control to receive Program Change, the first port input is directly forwarded to the currently selected output
