F aug7 — Paraphonic Synth

F aug7 is built from F – A – C# – Eb. 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: all 4 notes fit — root, 3rd, #5, b7 — one envelope shapes every voice.
