TB-3PO — web edition

A browser port of the TB-3PO Hemisphere applet (Ornament & Crime / Phazerville firmware, by Logarhythm & djphazer). Same seed = same pattern: the generator and PRNG are ported bit-exactly.

Unlocked (die): pattern re-randomizes on every RESET. Locked (lock icon): the 4 hex digits become editable — same seed, same pattern.

Density

−7: dense gates, root note only · 0: sparse, full scale · +7: dense, full scale. The slider sets the centerpoint; CV offsets it like the O&C's CV input.

Quantizer Q1

Transpose

Root = semitones after quantize · Deg = scale degrees, stays in scale
