Match a target Hammond drawbar silhouette by ear and eye, training the same registration instinct organ players use to dial gospel, jazz, and rock tones.
In the world
Jimmy Smith's signature tone on "Back at the Chicken Shack" is a drawbar registration you can dial from memory once you know the recipe.
Every famous organ sound is a fixed recipe. The widget shows a target silhouette of drawbar heights. Your rack's mixer faders are your drawbars. Copy the silhouette fader by fader and the patch should match the reference sound.
This is ear training disguised as knob twisting. After a few registrations you start to hear which partials are loud before you even touch the faders.
Did you know?
Session organists in the 1960s would tape strips of paper to their drawbars with preset positions marked in pencil - the analog ancestor of synth patch memory. Some players could reset all nine drawbars between songs in under two seconds without looking.

A mechanical orrery spins on the right - each planet is a harmonic, and its size shows the amplitude. Ghost orbit rings show the target registration. Use the sliders to resize each planet toward its ghost. When a planet matches, it turns green. Click a preset name to hear (and see) that registration instantly. Match all 8 and the star blazes with resonance.
