MOD·01 / Movement

PULSAR

Auto-pan that throws your sound into orbit. Chaos, Doppler and binaural width — the movement obeys physics, not an LFO.

// What it does

One pad. A whole physics engine.

PULSAR sends your signal into real 3D orbit around the listener. You steer a chaos field with the StellarPad and the sound flies — close and far, fast and slow — following physical attractors instead of a boring sine LFO. Simple on the surface, a genuine motion engine underneath.

StellarPad

The control surface. Drag to set the center of the orbit — the field flies around the point you pick.

Motion

One knob for energy. Couples chaos, distance and Doppler through orbital mechanics — turn it up and the whole system comes alive.

Rate / Sync

Free-running, or locked to your host tempo — from whole bars to fast cycles.

Shape

Morph continuously between four attractors: Orbit → Pendulum → Lorenz → Rössler. From clean circles to deterministic chaos.

Smear

A comet tail. Schroeder diffusion in the feedback path smears the trajectory into space.

Width / In Phase

Real head-shadow stereo width. IN PHASE collapses to mono-safe in one click.

// The physics

Movement you feel, backed by real acoustics.

No "3D" marketing. PULSAR uses the same psychoacoustics your ears use to locate sound in the real world.

Binaural engine (HRIR)

Convolution with head-related impulse responses places the sound outside your head — not just hard-panned left/right.

Head-shadow ITD

Inter-channel time delay (Woodworth) decorrelates L/R for width that stays mono-compatible.

Real Doppler, zero latency

Pitch emerges from modulating the propagation delay — no pitch-shifter, no latency. The fly-by is physics.

Deterministic chaos

Lorenz and Rössler attractors drive the path — erratic, never random, always musical.

True-peak safe

Lookahead limiting keeps inter-sample peaks in check, so it never clips your master.

Measured, not guessed

Phase correlation tuned from +0.79 (natural) to −0.46 (ultra-wide); the mono-safe path is verified by measurement.
