instrumentDef seems not to apply to instrumentSection

[SambaGodschynski]

repo

instrumentDef: _setName=p1 _onDevice=MyDevice _ch=1 _pc=1 _cc=8;
instrumentDef: _setName=p2 _onDevice=MyDevice _ch=2 _pc=1 _cc=8;
instrumentSection: mySection p1 p2;
instrumentConf: mySection mod <<yourModHere>>;

expected

the mod will be applied to "mySection"

actual

the mod is not applied

[SambaGodschynski]

it works when executed manually:

[
instrument: mySection;
{
    /mod: <<yourModHere>>/
    c, d, e, f, | g, a, b, c 
}
]
