Dual indicates that an instrument or module contains two identical or complementary sections. This can apply to oscillators, filters, envelopes, or channels, allowing parallel processing, stereo operation, or more complex sound design within a single unit.
Generator is a sound source that creates raw audio signals used as the foundation for synthesis. This can include oscillators, noise sources, or digital sound engines that are shaped and controlled to produce musical tones, textures, and effects.
A module is a self-contained unit designed to perform a specific function within a larger system. Modules are commonly used in modular and Eurorack setups, where each unit handles tasks such as sound generation, modulation, filtering, or control, allowing systems to be built and expanded piece by piece.
New Gear is unused and in original condition, supplied as it leaves the manufacturer. It is chosen for guaranteed reliability, full functionality, and the assurance of manufacturer support. For example, buying new ensures access to the latest design revisions, included accessories, and official warranty coverage.
An oscillator is the core sound source in a synthesizer, responsible for generating the raw audio signal that everything else is built from. It produces basic waveforms such as sine, saw, square and triangle, which can then be shaped and processed into more complex sounds.
What makes oscillators so important is their role in defining the character of a sound. Different oscillator types and designs can produce anything from smooth, pure tones to rich, harmonically complex textures. In modular systems, multiple oscillators can be combined, tuned and modulated to create evolving and expressive sounds.
Oscillators are simply great — fundamental, versatile and essential to synthesis. Whether you’re building basic tones or complex soundscapes, they are at the heart of your sound, and you will not be disappointed.
