The S704 is a module with two identical sections. Each section converts a incoming gate of any length to a trigger pulse. The pulse width is ONE sample. Which means that it’s dependent on the current sampling rate of your DAW and oversampling in SoloRack.
This functionality is useful in some situations where where the receiver of the gate is level sensing. For example, It could be used to RESET a sequencer and immediately start it again instead of stopping it for the duration of gate.
