The 569LE Quad Lag Expander equips all four tracks of the composition tool 569 Quad Sequential Voltage Source with portamento functions. In detail, the module adds a gate input, a potentiometer for varying the glide time and two switches per channel. The latter make it possible to toggle between several modes of operation. One switch is usable for selecting normal or gate mode. Alternatively, it is possible to turn the portamento effect off. The second control element determines, whether the lag function shall be active at rising and / or falling edge.
