The laws regulating original outputs for capital were strictly drawn in Great Britain and on the continent of Europe; in America they were drawn very loosely.
Different outputs can be selected using the push-button switch.
The table gives the outputs in metric tons of the most important producers in 1900 and 1905 (from Rothwell, Mineral Industry, 1908).
Other feature refinements include added output busses, with up to 8 stereo outputs now available within the virtual mixer of the host application.
I guess things could be a bit more complicated if slices of arrays are used for inputs and outputs, but maybe still doable.
