INTRODUCTION: 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.

Filter Structure Etna comprises three analog multi-mode lters, including a low-pass lter with a 24 dB/octave (4-pole) slope, a band-pass lter, and a high-pass lter with a 12 dB/octave (2-pole) slope. The lter circuits deliver ultra-clean sound due to the low distortion of the SSI2164, combined with rail-to-rail op-amps to maximize the threshold without distorting the waveforms.

Etna can be synchronized with an external clock by connecting a signal to the CLOCK input jack. It will advance to the next stage with each pulse, allowing you to send trigger patterns to play the snapshots. By holding the encoder for 3 seconds, you can divide the clock rate to enable slower morphing through the snapshots.

The image displays the analog controls and outputs for the filters. These controls will sum the values with the digital adjustments, enabling real-time, expressive modifications to the parameters of each saved snapshot. This attribute not only enriches the morphing process but also delivers a tangible, live interaction that injects substantial depth and intricacy into live performance settings.
