Make Noise STO

Analog sine wave VCO in Eurorack format

• Triangular core oscillator with outputs for SINE, SUB and Variable SHAPE
• Unique Variable SHAPE circuit for subtle timbre variations on even and odd harmonics
• Linear FM input with depth control for expressive modulations
• EXPOnential input for deep FM, SYNC sweeps or sequence transposition
• Dedicated SUB-Oscillator for massive basses
• S-Gate input for gating or sync of SUB-Osc. independent of other outputs
• Hard SYNC circuit that, combined with Linear FM and Variable SHAPE, generates harmonically rich sounds
• Ideal for pairing with modules such as MMG or Optomix

Make Noise STO: The VCO that sculpts your sound with analog elegance

The Make Noise STO (Sub-Timbral Oscillator) synthesizer module is a compact Voltage Controlled Oscillator designed to generate SINE waves, Variable wave-SHAPEs, SUB-Octave, Oscillator SYNC and Linear FM. Fully analog, the STO is the subtler and more melodic companion to the harmonic complexity of Make Noise's DPO, offering precise control to sculpt your sound with unparalleled refinement.

From sine wave purity to harmonic richness

At the heart of the STO is its triangular core, which provides a solid foundation for all its outputs. The SINE output offers fundamental timbral purity, while the innovative Variable SHAPE circuit allows even and odd harmonics to be subtly introduced and modulated, transforming the sine wave into unique and dynamic timbres. Add to this a dedicated SUB-Oscillator for deep and powerful bass foundations, with an S-Gate input for independent control of its gating or synchronization.

Modulation and synchronization for advanced sound textures

The STO excels at modulation thanks to its versatile FM inputs. The Linear FM input offers precise control over modulation depth, while the EXPOnential input lends itself to extreme FM, spectacular SYNC sweeps, or accurate transposition of your sequences. The Hard SYNC circuit, in combination with Linear FM and Variable SHAPE, opens the door to a world of harmonically complex and distinctive sounds, making the STO an essential element for those seeking versatility and character in their Eurorack system. It is the perfect companion to modules such as Make Noise MMG or Optomix for smooth integration into your workflow.
