Patching Panda Etna

A triple-control analog morphing filter.

20 HP Eurorack module

A triple-control analog morphing filter that saves filter states as snapshots and recalls, morphs, or sequences up to eight stages by hand, CV, or clock.

Features

  • Stores complete filter states as snapshots across up to eight stages.
  • Provides shared frequency and FM control for all three filters.
  • Uses Q compensation to maintain output volume as resonance increases.

Controls & Jacks (49)

  • Edit All— Makes fader adjustments apply to every snapshot.
