THE LEIBNIZ BINARY SUBSYSTEM GERA binary product commander operator’s manual rev. 1989/X5/1.
module explained SALUT reversed power connection; flipping the 16pin header may cause serious damage to other components of your system because it will short-circuit the +12V and +5V power lines. Always pay close attention to the proper orientation of your ribbon cable on both sides! Thank you for purchasing this Xaoc Devices product. Gera [ˈgɛra] is a component of the Leibniz Binary Subsystem. It works by processing data in the Leibniz bus and requires a connection to other Leibniz modules.
front panel overview tive gate is logic 0. Although Gera will work with smoothly changing signals within the entire range of Eurorack voltages, we recommend plugging standard Eurorack gates and square waveforms for the best results. fig. 1 Above the input jacks is a bank of eight illuminated manual tact switches 2 , each corresponding to a gate input of the same number. Pressing the button toggles between taking the input gate signal as-is and taking the inverted state of it.

The same masking of bit #7 occurs when the gate signal is inactive (0V), and is not manually inverted.
