Mantra II is an extremely versatile Serge system and an ideal start in the Serge Modular music system. It comprises a number of modules designed or redesigned by Serge in 2020 to 2023 like the GTS and the GTO push the boundaries further than ever before.

The Serge MANTRA II is an evolution of the Mantra panel that is even more powerful than its predecessor. It comprises a number of modules and functions that have never been available before.

Sequencer 8 (SEQ8): the classic Serge Sequencer optimized for audio speeds and with a new GATE output that allows the pushbuttons to be used asa mini-keyboard.
GTS XL: Serge reinvented his famous Serge DSG module, based on a completely new core for ultimate tracking and speed. GTS now provides slopes as fast as 12us and sawtooth tracking over 6 octaves. The XL version features SINE(oid) outputs, a new TRIanguloid output, additional VC BOTH inputs, a PULSE OUT in the top half plus an integrated Serge PEAK & TROUGH. Most likely the most versatile and powerful Serge module ever.
GTO: another iconic Serge module, the Smooth & Stepped Generator (SSG), reinvented by Serge, optimized for speed and tracking - and of course, audio. The SSG is one of the deepest Serge modules, providing a number of uses: as oscillator / LFO, audio filter, glide, sample-and-hold and many more. The GTS adds 1V(Oct inputs, new oscillator and sample modes for the lower (stepped) sides, SYNC for the smooth side and insane speeds... In combination with the Serge Noise, the SSG can be patched as a Random Voltage Generator.
Serge Noise (NOI): white noise, pink noise and a crazy saw as S/H source.
GTS: the Dual Slopes formerly knows as DSG a.k.a. “TimeGen Osc” have also been upgraded to GTO, offering the same improved tracking and stability in only 2” width.
Active Processor (ACPR): The top section is a new 2017 version design by Serge by Serge himself, improving the original linear crossfader. The bottom section is a new FLIP-FLOP module, that takes a pulse sequnce as input and generates alternating gate signals on the two outputs for a number of uses, such as pulse divider (/2) or sub-oscillator.
Variable Q Filter (VCFQ): the most popular, extremely versatile Serge filter offering simultaneous low-pass, high-pass, band-pass and notch (band-reject) outputs. The resonance (Q) of this filter is dynamically variable by manual or voltage control - now with an attenuverter (integrated CV processor). The VCFQ traditionally has two signal inputs. One incorporates an automatic gain control to prevent the filter from overloading at high Q settings. The second input has a level control so that the percussive effects of overloading the filter can be exploited. For Mantra II, we added an additional (fixed gain) input.
X-Fader (XFAD): an audiophile version of Serge’s equal-power cross fade unit, featuring a balanced output. The exponential VCA section offers the unique Serge VCA response and beautiful overdrive possibilities.
