F# 9b5 — Paraphonic Synth

F# 9b5 is built from F# – G# – A# – C – E. On the Paraphonic Synth 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 Paraphonic Synth carries 4 keys sharing one envelope across 49 keys (C2–C6): every key you hold rides the same amplitude contour, which flatters swells and blurs syncopation — the charts say so out loud.

Under this keyboard's own voice architecture the engine reports: dropped: root — kept: 9th, 3rd, b5, b7 — one envelope shapes every voice.
