Combination Matrix Generator

Map a chain of pitch-class positions to a 2D matrix using a diagonal-plus-right layout. Enter positions as hex strings separated by |, spaces, commas, or slashes — e.g. 094|156|21|79B|A52.

Chain Input

Each position is an unordered set of pcs (0–9, A=10, B=11). Use any separator between positions.

Rows

Columns

Rows × cols must be ≥ number of positions in the chain.

PC Focus

Pitch Class (0–9, A–B)

Apply Focus Clear Focus

Highlights cells containing the chosen pc; flags rows/columns where its count ≠ 1 in red.

Transposition & Inversion

Transpose by n (1–11)

Apply T_n Invert (I)

T_n: adds n semitones (mod 12) to every pc. I: maps x → (12 − x) mod 12.
