Nope. To support midi endpoint vector icon, you should have:
1) at least one endpoint coming with a vector icon in its properties
2) an app able to display endpoint icon, and supporting vector icon type.
For 1), every MIDI app registering an endpoint should have to be
enhanced to publish a vector icon.
For obvious reason, as hinted by this icon request, midi_server will
be the first:
DeviceWatcher::_SetIcons(BMidiEndpoint* endpoint)
{
BMessage msg;
- // TODO: handle Haiku vector icon type
+ msg.AddData("be:vector_icon", B_VECTOR_ICON_TYPE, fVectorIcon->Bits(),
fVectorIcon->BitsLength());
msg.AddData("be:large_icon", B_LARGE_ICON_TYPE, fLargeIcon->Bits(),
fLargeIcon->BitsLength());
msg.AddData("be:mini_icon", B_MINI_ICON_TYPE, fMiniIcon->Bits(),
fMiniIcon->BitsLength());
endpoint->SetProperties(&msg);
}
But any MIDI app driving an endpoint, like "MIDI keyboard" etc could
attach an icon to their endpoint properties
in the same way.
For 2), indeed, PatchBay is our best candidate, MeV could be another
one in a near future.

From a resource, check src/kits/interface/Alert.cpp, BAlert::_InitIcon()
Except that rawIcon should be retrieve from endpoint's properties, aka
from a BMessage, in PatchBay.

Replacing a icon by a better looking one is never an issue.
