The switches and sockets located in the center expand Terminal's channels. Upper part corresponds to Airplane A and the bottom to Airplane B.
The switches assign the CV input of each section individually either to the duration parameter or the shape parameter.
The "ends" sockets are outputs which emit a trigger after finishing the attack or the decay phase.
If you set the VCF mode switch into upper position the corresponding lowpass gate of the Terminal will turn into a low pass filter with a slope of -12dB per octave.
The Gateway not only is an expaner module for the Terminal but it might as well be used as a dual 1+1 mixer for CVs or audio. Signals at the inputs Key In and CV In as well as the offset voltage set with the potentiometer are mixed. The mix is available at the Drop Out socket.
This is used to easily tune oscillators to the note "A" just by pressing a button, working with the mixer section. For instance conenct the 1V/oct output of a MIDI/CV interface to the Gateway's Key In socket. Connect Drop Out with the VCO's 1V/octave input. Patch a VCO waveform output to the Tune In socket at the Gateway. Press the note A at the MIDI keyboard. Press the Gateway's autotune button. That's it.

plus the end-of-attack, end-of-decay trigger outputs
