 * The instruments the emulator offers for the green Welte, in three groups that
 * answer three different questions and must not be listed as one.
 *
 * A **genuine** instrument is fitted to the drawn nuance line of a green roll
 * and says what a green Welte did. A **derived** instrument is fitted so that
 * the green code of a recording reproduces what the fitted T-100 emulator makes
 * of the *red* copy of the same recording, and says what Welte's editor meant
 * the green roll to sound like; its provenance names the T-100 instrument it
 * inherits, since it is only as good as the red reading behind it. The
 * difference between the two, in the printed ordinate both scales share, is how
 * far the transfer of a red reading onto the green mechanism succeeded.
 *
 * Both are now fitted, on `welte-mignon-emulator` 1.1.0: five genuine
 * instruments, one per lined green roll that could be read, a consensus across
 * them, and the derived instrument for the one recording issued on both scales.
 * The **unfitted** starting values remain as a third group, arithmetic from
 * Welte's regulation controls with no green roll behind any of it, and a curve
 * produced with them says so in its own `instrument` field.
 *
 * **Prefer a roll's own instrument where the roll is one of the five.** The
 * green instruments disagree with one another far more than the red ones do:
 * the consensus is held out at 0.121 on the bass where the per-roll instruments
 * are 0.029 to 0.066, because a shared mechanism describes none of them well.
 * That spread is a property of the instruments rather than of the fit, and
 * Gottschewski's finding that they were out of regulation is visible in it.
