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-format voltage-controlled oscillator (VCO) module, produced from 2008 to 2026. It functions as a sub-timbral oscillator, designed to generate sine waves, variable wave-shapes, sub-octaves, and support oscillator sync and linear FM. The module is similar in design to a single channel of the Make Noise DPO but with specific refinements. It features three outputs: sine, sub, and variable shape, along with a linear FM input with depth control and a reset input that accepts audio-rate signals. Known for its compact size and analog signal path, the STO has been described as a hidden gem in the Make Noise lineup.

Design
The STO uses a triangle-core analog oscillator design and is considered Make Noise's classic VCO. It provides waveshaping capabilities and is built for integration into modular systems requiring precise control over pitch and timbre.
Context
While Make Noise has released more complex oscillators since its introduction, the STO has maintained a reputation as a compact yet powerful module. It remains valued for its simplicity and versatility within the Eurorack ecosystem.
Market
The STO was originally priced at $199 new, with used units selling for around $140. It continues to be used by professional artists and is regarded as a capable entry-level oscillator in the Make Noise lineup.
