The Serge GTO is a newly designed, complex multi-functional module which can be patch programmed to provide various slew and sample functions both for audio and CV signals, but also act as a (dual) oscillator or filter or bitcrusher or ... It is one of the essential Serge modules. The GTO is an offspring of the famous Serge SSG.

The Smooth section will place a positive and negative slew on input voltage transitions for lag effects, voltage controlled portamento and for low frequency filter applications. In Cycle-mode (cycle jack patched to the input), the Smooth side “will oscillate yielding a voltage controlled triangle wave LFO. A high level into the HOLD input will enable the Smooth Function to be used as a track-and-hold circuit with voltage controlled slew rate.

The Stepped function can be used as a sample-and-hold with voltage controlled slew rate limiting. In Cycle mode, a pulse applied to the Sample input will generate complex staircase waveforms for control voltage applications and for use as audio signals.

Each side has a temperature-compensated 1V / Oct input for use as an oscillator with a frequency range of up to 20kHz (left) and 8kHz (right). Each side tracks over 5 or 6 octaves.

The Coupler is an internal comparator which compares the output levels of the Smooth and the Stepped Generators. This output is useful for generating complex control voltages or random voltages.
