Stereo Modulated Filter

What is Riemann’s Grave? At its core, it’s a stereo filter pedal. But there’s a few things that make it truly unique.

The multi-mode filter can be modulated in some interesting ways. A random sample and hold wave or a Wandering Sine can be used for modulation. There’s plenty of resonance on board to whistle and howl with.

The Zeta Function can add mild saturation or distortion in three ways: wave folding, bit crushing, or octave up distortion. This gives the filter lots of harmonic content to work with. The wavefolder option can go from putting some crispy edges on your signal all the way to splashy white noise. The bit crusher also reduces the sample rate for fidelity grit. The octave distortion has lots of upper mid and high frequency content to feed the filter.

All three flavours of Zeta will add dimension and depth to clean or saturated signals

The Jitter feature creates movement for the other parameters, and is geared toward making unexpected things happen.

Riemann’s Grave is a fun little thing that has a mind of its own.
