D# m(maj9) — 8-Voice Polysynth

D# m(maj9) is built from D# – E# – F# – A# – C##. On the 8-Voice Polysynth those tones land as real keys, and every chart below names the tone under each one — root position first, then the shapes that earn their place: inversions, the open spread, the 1-3-7 shell.

The 8-Voice Polysynth allots 8 voices across its 61 keys (C2–C7): enough for most qualities, but the extended colors make the reducer earn its keep — each chart shows the arithmetic.

Under this keyboard's own voice architecture the engine reports: all 5 notes fit — root, 9th, b3, 5th, 7th.
