Perhaps I can clarify a bit of the terminology.

"Plenum" or "In organo pleno" and "Ripieno" come from the German Baroque
era. They mean a full Principal chorus (Prestants, Octaves, Quint 2
2/3', not 5 1/3' !, Mixtures), combined with some Flute stops (Quintaton
16', Flute 8'), and depending on the character of the piece, one or more
manual Reeds. In the Pedal you have to draw the strong Reeds like
Posaune 16'.
In later time, say Reger c.s., this term is used as the final, strongest
sound and that quite equals the "Tutti", then meaning full organ but of
course, as pointed out earlier without undulating stops and without some
very soft charachteristic stops. Usually also without Flute's 4' (on a
real organ a Flute 4' only consumes a lot of air and adds practically
nothing to the Tutti)

"Plein jeu" and "Grand jeu" are stemming from the French Baroque music.
In a "Plein jeu" you have the principals ( on a 16' basis), bourdon 8'
and all the different mixtures (Cymbale etc.); no reeds. In the pedal
only a Trumpet 8', coupled to the manuals; French organs from this
peroid had no other pedal stops.
In a "Grand jeu" you have the Trumpets, Clairons (4') plus tertiary
aliquots like Cornet or Sesquialter; no principals or bourdons.

"Tutti" in French romantic music (and later) means all manuals coupled,
with foundations (principals, flutes etc.), mutations and reeds and sub-
and supercouplers. No undulating stops and no soft charachteristic stops
like Voix humaine, quite similar to the German romanitcism. Only the
sound is very different: in French organs the Reeds are very strong and
dominant and the Mixtures are quite soft in comparison; in German organs
from this time the Reeds are fairly weak and the upperwork is stronger.

Kind regards,
Bert
