HOLOCENE ELECTRONICS SEICHI

Complex Filter and wavefolding VCA

What is Seiche?(pronounced say-sh)


Seiche is a 16HP “Complex Filter” combining traditional analog filtering with nonlinear wave shaping. Each of the two channels offers:

• OTA Based 2-pole State Variable Filter (Switchable between Lowpass, Bandpass, Highpass)

• Integrated Wavefolder

• Normalization for FM or AM between channels
  switchable using a toggle switch.

• Ping input for percussive tones
Think of it as a dual voice core, filter sculptor, waveshaping distortion module, and character rich Lowpass gate all in one.
