Etna is an advanced triple control analog multimode morphing filter, meticulously designed for precise and dynamic sound shaping. It allows for rapid or smooth transitions between diverse filter settings, known as snapshots.

Each snapshot comprehensively defines all of the filter’s parameters, which can be adjusted either swiftly or gradually. These transitions are controlled through an applied voltage or clock and triggers, with the flexibility to use up to eight distinct stages for creating complex filtering effects in a variety of audio applications.

In addition to its morphing capabilities, Etna incorporates analog controls that enable real-time, expressive modifications to the parameters of each saved snapshot. This enhancement not only enriches the morphing process but also provides a tactile, live experience that adds significant depth and nuance to the audio output, making it a powerful tool for both studio and live performance settings.
