Would probably help if I showed the file :). I'm guessing the
problem
is it's not allowed to use a variable inside of the braces after
the \with
command, but I don't understand why.
Correct. A \with clause may contain only
a) property operations
That's changing context or grob properties
b) context definitions
That's things like \consists, \accepts etc.
This was one of my questions as a newbie
three years ago next week! The answer came
from Nicolaus Sceaux, see

A music function has to return some music,
so you need to pass the ossia music to the
music function too, and include the \new Staff
as well, like this:
ossia = #(define-music-function (parser location staffName music)
(string? ly:music?)
#{
\new Staff \with {
alignAboveContext = #$staffName
\remove "Time_signature_engraver"
fontSize = #-3
\override StaffSymbol #'staff-space = #(magstep -3)
\override StaffSymbol #'thickness = #(magstep -3)
}
$music
#})

\version "2.12.2"
ossia = #(define-music-function (parser location staffName)
(string?)
#{
alignAboveContext = #$staffName
\remove "Time_signature_engraver"
fontSize = #-3
\override StaffSymbol #'staff-space = #(magstep -3)
\override StaffSymbol #'thickness = #(magstep -3)
#})
myMelody = \new Staff = main {
\relative c' {
c8 d e f g a b c |
<<
{
d1
}
{
\new Staff \with { \ossia #'main } {
\relative c' {
\clef bass
c4 d e f
}
}
}
>>
}
}
\score {
\myMelody
\layout {
}
}
