Thanks, Mikael. That works nicely. Note: I changed
\definefallbackfamily [mainface] [mm] [Brill]
[preset=math:lowercasegreeknormal]
to
\definefallbackfamily [mainface] [mm] [Brill]
[preset=math:uppercasegreeknormal], since Knuth/TeX sets Greek capital
letters upright.

Assuming that it is possible, I have been trying to substitute the Greek
letters of my main font for those used in the math font. (if it works,
it
should look better on the page than what I have now.)
So, what have I missed/messed up in the following?
\definefontfamily[mainface][serif][Brill][
[protrusion=quality,
expansion=quality,
mode=node,
force=yes,
]
\definefallbackfamily[mainface][mm][TeX Gyre
Pagella][preset=math:digitsnormal,features=f:oldstyle]
\definefallbackfamily[mainface][mm][Brill][range=0391-03A9,03B1-03C9]
\definefontfamily[mainface][mm][TeXGyre Termes Math]
\setupbodyfont[mainface,36pt]
\starttext
\emph{λ α μ β δ α}
\m{λαμβδα}
0123456780
\m{0123456780}
\stoptext

What if you change
\definefallbackfamily[mainface][mm][Brill][range=0391-03A9,03B1-03C9]
to
\definefallbackfamily [mainface] [mm] [Brill]
[preset=math:lowercasegreeknormal]
\definefallbackfamily [mainface] [mm] [Brill]
[preset=math:lowercasegreekitalic]
That seems to work here with your example. By the way, I have not seen
the Brill font before. It was very nice!

Hi!

I think there might be a small piece of misunderstanding (either on
your side or on mine). Try the document

\definefontfamily[mainface][serif][Brill][
                        [protrusion=quality,
                        expansion=quality,
                        mode=node,
                        force=yes,
                        ]

\definefallbackfamily [mainface] [mm] [Brill] [preset=math:lowercasegreeknormal]
\definefallbackfamily [mainface] [mm] [Brill] [preset=math:lowercasegreekitalic]
\definefallbackfamily [mainface] [mm] [Brill] [preset=math:uppercasegreeknormal]
\definefallbackfamily [mainface] [mm] [Brill] [preset=math:uppercasegreekitalic]

\definefontfamily[mainface][mm][TeX Gyre Termes Math]

\setupbodyfont[mainface,10pt]

\setuppagenumbering[state=stop]

\starttext
αβΓΔ{\em αβΓΔ}$\alpha\beta\Gamma\Delta$ (default, upper case greek is upright)

\setupmathematics[
ucgreek=italic,
]

αβΓΔ{\em αβΓΔ}$\alpha\beta\Gamma\Delta$ (now uppercase greek is in italic)

\setupmathematics[
ucgreek=normal,
lcgreek=normal,
]

αβΓΔ{\em αβΓΔ}$\alpha\beta\Gamma\Delta$ (now both uppercase and
lowercase greek are in upright)

\stoptext

The definefallbackfamily commands do not set what kind of greek
letters we get, but only from what font the corresponding range comes
from. This is at elast how I understand it.

Best

Mikael
