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 Dual GTO consists of identical GTOs plus a Serge Noise and a Mixer that provides the sum of the two top sections and of the two bottom sections.

Each Smooth section (top) 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.

Each 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. In the GTO, however, the right side can to some extent - in particular when the SMPL switch (14) is in CENTER position - behave like a “smooth” side.

Each section has a temperature-compensated 1V/Oct input for use as an oscillator with a frequency range of up to >20kHz (top) and 8kHz (bottonm). Each section tracks over 5 or 6 octaves, so the Dual GTO can be used as a quad oscillator.

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.

Some details:

  • 2 Serge GTOs, designed by Serge Tcherepnin in 2022
  • Authentic SERGE design
  • Increased audio range (up to >20kHz)
  • Suited for use as oscillators
  • Can be patched as 2 Random Voltage Generators (RVGs)
  • Temperature compensation
  • 4x4 format (4U - this is not Eurorack!)
  • Power consumption: 100mA @ +12V, 95mA @ -12V
  • fits in a superslim boat
  • needs about 100mA
  • 4x4 format (4U high - this is not Eurorack!)
