The STO is Make Noise's classic VCO. It is similar to a single channel of the DPO, but with a few adjustments. It has three outputs: a dedicated sine output, a square wave sub-octave output, and a waveshaped output that morphs from a soft triangle to something between a triangle and square wave. There are both linear and exponential FM inputs, as well as a sync input. The waveshaping circuit is also voltage controllable, providing timbral shifts without any filter. It tracks musically using the 1V/Oct input over 5 octaves. The sub-octave output is kept separate when the sync input is used, so the sub-octave has its own sync input, S-Gate. For those wanting the sound of Make Noise without the price of a DPO, the STO is the perfect solution.

STO FEATURES

• Compact Voltage Controlled Oscillator
• Triangle core with outputs for sine, sub, and variable shape
• Unique variable shape circuit ripples even and odd harmonics for subtle timbral shifts
• Linear FM input with depth control
• Exponential input for deep FM, sync sweeps, or transposition of sequences
• Sub-oscillator delivers maximum bass
• S-Gate input for gating or sync of sub-oscillator independent of other outputs
• Hard sync circuit which, combined with linear FM and variable shape, yields harmonically rich sounds
• Pairs well with the MMG or Optomix
