Power
Sound carries real power, in watts. An average drumcap gives 10 W. A machine catches all of a source within 2 blocks, a quarter at 4, a ninth at 6: power falls with the square of the distance, and off-tune or behind walls it catches less.
Machines near one source share it: two crushers by one drumcap run at half speed each.
Each machine needs so many watts for full speed: crusher 10, hybridizer 8, incubator 6, growth chime and mutagen 5. An idle machine takes nothing. A source burns biomass for what is taken from it: the full cost while machines use all its power, a tenth while it plays for nobody.
A resonator only measures: click it to see how many watts a machine would get there.
