Block Rotator

A reverb that breathes, mutates, and orbits

A feedback delay network reverb built on an 8-channel diffusion core, with ten proprietary spatial algorithms, pitch-shifting tails, and an automated parameter-morphing crossfader.

What it does

8-Channel Diffusion Delay Feedback Network

Eight parallel delay lines feed a diffusion matrix, producing dense, evolving reverb tails that range from tight ambience to vast, disintegrating spaces.

10 Proprietary Spatial Algorithms

Two banks of five. Max Diffusion — Cyclops, Apshai, EyeDescent, Scarab, DeathIbis — scatters signal across the spectrum into lush washes. Max Rotation — BlockRotate, Schistdisc, BloodLoom, Sekhmetal, Uncoiling — builds orbiting, spiralling stereo fields with real physical motion.

Pitch-Shifting Reverb Tails

Transpose the feedback path so repeats drift upward or downward, producing shimmering, endlessly ascending spaces or subterranean descents.

Resonant Multi-Mode Filter

Shape the feedback path with a resonant filter, sculpting the tone of every repetition as it decays.

Parameter Morphing Crossfader

Capture two complete parameter states and crossfade between them — manually, via LFO, or under host automation — for transitions no single knob can produce.

Real-Time Visualization

Watch the network work: live displays of the diffusion field, stereo correlation, and level metering.
