Hi,
Myriad Pro is not working in recent version of ConTeXt (the same
source works well in last release).
Here is the code:
\starttypescript[all][myfont][name]
        \definefontsynonym[Myriad][MyriadPro-Regular]
        \definefontsynonym[MyriadBold][MyriadPro-Bold]
        \definefontsynonym[MyriadItalic][MyriadPro-It]
        \definefontsynonym[MyriadBoldItalic][MyriadPro-BoldIt]
\stoptypescript

\starttypescript[sans][myfont][name]
        \definefontsynonym[Sans][Myriad]
        \definefontsynonym[SansBold][MyriadBold]
        \definefontsynonym[SansItalic][MyriadItalic]
        \definefontsynonym[SansBoldItalic][MyriadBoldItalic]
        \definefontsynonym[SansSlanted][MyriadItalic]
        \definefontsynonym[SansBoldSlanted][MyriadBoldItalic]
        \definefontsynonym[SansCaps][Myriad]
\stoptypescript

\definetypeface [myfont] [ss] [sans] [myfont]   [default]
\usetypescript[myfont]
\setupbodyfont[myfont,ss, 12pt]
\starttext
\input zapf
\stoptext

Here is the log:

Hope this helps debugging.
