Make Noise STO (2008–2026)
A compact Eurorack voltage-controlled oscillator with triangle-core design and multiple waveform outputs
Overview
The Make Noise STO is a Eurorack voltage-controlled oscillator (VCO) module, produced from 2008 to 2026. It is a sub-timbral oscillator. It generates sine waves, variable wave-shapes and sub-octaves, and it supports oscillator sync and linear FM. The design is similar to a single channel of the Make Noise DPO, with some refinements. There are three outputs: sine, sub, and variable shape. There is also a linear FM input with depth control, and a reset input that accepts audio-rate signals. It is compact, the signal path is analog, and it has been described as a hidden gem in the Make Noise lineup.

Design
The STO uses a triangle-core analog oscillator and is considered Make Noise's classic VCO. It has waveshaping built in, and it is made for modular systems that need precise control over pitch and timbre.
Context
Make Noise has released more complex oscillators since the STO came out, but the STO has kept its reputation as a compact and powerful module. It is still valued for being simple and versatile.
Market
The STO was originally priced at $199 new, with used units selling for around $140. Professional artists still use it, and it is regarded as a capable entry-level oscillator in the Make Noise lineup.
