Black Noise Modular - Eclipse

The Eclipse is an analog stereo morphing oscillator that combines the sound character of classic analog oscillators with modern features for advanced sound design.

At the heart of Eclipse is a high-precision analog triangle oscillator that tracks accurately over ten octaves. The module provides the full set of inputs and outputs you’d expect from a high-quality VCO, ensuring reliable integration into any Eurorack system.

A central feature of Eclipse is its custom waveshaper, inspired by the EMS VCS3. Instead of a conventional wavefolder, this circuit generates rich and complex harmonics with wide-ranging sonic possibilities and dynamic control.

The waveshaper concept is expanded into the stereo domain. The result is a dedicated stereo section that allows waveforms to move and spread across the stereo field while maintaining balance, adding a strong spatial dimension to synthesis.

Eclipse offers full CV control for all parameters, with smart normalization that enables global modulation from a single source. Additional functions such as XFM, ULFO, Stereo Pulse Array Modulation, Stereo Pulsed Saw Modulation, and RM/AM modes extend the module’s capabilities far beyond those of a conventional VCO.
