The GTS from Random*Source Serge Modular is a refreshed and revitalised edition of maybe the most popular circuit design in Eurorack synthesisers, the Serge Dual Universal Slope Generator (DUSG).
Serge himself redesigned his classic architecture to add even more functionality and phenomenal improvements to the multitude of voltage-mangling tasks the DUSG was already capable of. The GTS has all the same flexible functionality of two comprehensive slope generators, with a redesigned core to add incredibly stable 1V/oct pitch tracking for use as a complex oscillator. Temperature compensation has also been added for stability, as well as improvements to the time range of each function.

Two identical slope generator sections on either side of the module provide the best version of this circuit yet from Serge. Each gives you main outputs as well as bipolar, inverted outputs. The function may be triggered by the TRIG inputs to create envelope shapes, or cycled to create LFO signals. And END trigger output sends a gate when the fall function ends, remaining high for most of the rise function. Rise and fall are both simultaneously, both slope generators are optimised for use as an oscillator with Pulse waveform outputs and 1V/octave inputs.

The GTS really starts to diverge from its predecessor with the addition of two more helpful Serge voltage utilities: a CV processor and mixer, as well as the Serge Peak and Trough circuits. If you're familiar with the DUSG or its most famous noise-making offspring Maths, the combination of cycling function generators and a robust CV processor should be music to your ears. This added middle section offers a SUM output which mixes both slope outputs with two auxiliary inputs, which paired with attenuverter control for each channel is capable of creating very complex CV signals from a few simple sources. The comparator functions take this even further, with the MAX output comparing AUX1 and the main outs to send the highest current value, and the MIN output comparing AUX2 with the main outs to send the lowest current value.
