symbol.

The register names in the default \discant
register set have
modeled after numeric Swiss notation like depicted in
http://de.wikipedia.org/wiki/Register_%28Akkordeon%29, omitting
the slashes and dropping leading zeros.
The string name is basically a three-digit number with the
lowest digit specifying the number of 16' reeds, the tens the number
of 8' reeds, and the hundreds specifying the number of 4' reeds.
Without modification, the specified number of reeds in 8' is centered
in the symbol. Newer instruments may have registrations where 8' can
be used either within or without a tone chamber, ‘cassotto’.
Notationally, the central dot then indicates use of cassotto. One can
suffix the tens' digits ‘1’ and ‘2’ with ‘+’ or
‘-’ to indicate clustering the dots at the right or left
respectively rather than centered.

The default bass register definitions have been modeled after the
article http://www.accordions.com/index/art/stradella.shtml
originally appearing in Accord Magazine.
The underlying register model is
This kind of overlapping arrangement is common for Italian instruments
though the exact location of the octave breaks differ.
When not composing for a particular target instrument, using the five
reed definitions makes more sense than using a four reed layout: in
that manner, the ‘Master’ register is unambiguous. This is
rather the rule in literature bothering about bass registrations at
all.

The main use is for four-reed standard bass instruments with reedbank
layout
Notable instruments are Morino models with MIII (the others are
five-reed instead) and the Atlantic IV. Most of those models
have three register switches. Some newer Morinos with MIII might have
five or even seven.
The prevalent three-register layout uses the middle three switches
‘Tenor’, ‘Master’, ‘Soft Bass’. Note that the sound is
quite darker than the same registrations of ‘c,’-based
instruments.

The main use is for five-reed standard bass instruments with reedbank
layout
This tends to be the bass layout for Hohner's Morino series without
convertor or MIII manual.
With the exception of the rather new 7-register layout, the highest
two chord reeds are usually sounded together. The Older instruments offer
5 or 3 bass registers. The Tango VM offers an additional
‘Solo Bass’ setting that mutes the chord reeds. The symbol on
the register buttons of the Tango VM would actually match the
physical five-octave layout reflected here, but it is not used in
literature.
Composers should likely prefer the five-reed versions of these
symbols. The mismatch of a four-reed instrument with five-reed
symbols is easier to resolve for the player than the other way round.

This is primarily the register layout for the Hohner “Gola” model.
The layout is
The registers are effectively quite similar to that of
\stdBass
. An additional bass reed at alto pitch is omitted
for esthetical reasons from the ‘Master’ setting, so the symbols
are almost the same except for the ‘Alto/Soprano’ register with
bass notes at Alto pitch and chords at Soprano pitch.
