Gate Expander
The Gx (Gate Expander) adds 8 additional Gate/Trigger/Clock/Logic outputs to compatible modules like the Metropolix.
It connects via ribbon cable to the I2C expansion port of select modules in the intellijel product line.
On Metropolix you can edit and configure the functionality under the "MX" menu. E.g. transport pulses, per stage gate, mod lane clocks etc.
These merchants probably sell this module. Huh?
