These patchable works in the Filanthropoid series provide evan more possibilites than previous units. This Beauty has been hand-crafted with durability and ease of play in mind.

The sound produced by these monsters is phenomenal and continues to amaze us.

Waveforms (individual, or multiple layers) can be captured and maintained, often intermodulating in beautiful and/or disturbing ways. Super sensitive knobs let you filter through tons of sounds and glitchscapes. Albums are waiting to be created here as the sound is quite different from anything else you'll find. A heavanly palette of glitchscapes await.
