Live value readout while dragging
While you drag any of the rotary knobs (the tone-shaper knobs -- Bright, Damp, Length, Sympathy, Body, Width, Volume, Mix -- and the four wind rotaries -- Wind, Turbulence, Gust, Breath), a small floating value box appears just above the knob and tracks the value live as you turn it, in the same unit-aware form as the value-mode tooltip (e.g. "Volume: 70 %", "Length: 90 cm"). The box disappears when you release the knob. This works regardless of the tooltip mode above, so you always see exactly where you are landing without waiting for a hover.
The same floating value box appears when you drag a tuning peg up or down to fine-tune a string, showing the live note and cents (e.g. "A3 (+12 ¢)") and disappearing on release.
The box also appears when you nudge a knob with the arrow keys (see Keyboard Control below), and disappears when you let the key go.
