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.
