A maj7add13 — Mono Synth

A maj7add13 is built from A – C# – E – F# – G#. On the Mono 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 Mono Synth sounds one voice across its 37 keys (C2–C5), so a chord is never a stack here — it is a sequence, and the charts number the order your fingers roll.

Under this keyboard's own voice architecture the engine reports: arpeggiated — 5 notes rolled low to high: root, 3rd, 5th, 13th, 7th.
