Due to lack of IDL implementation for overloaded methods, this doesn't work.
Although this is a hack, I think the following IDL will work for you:

[RaisesException] MIDIInput getInput([StrictTypeChecking] DOMString target);

Thanks.
I filed a bug on this;
https://code.google.com/p/chromium/issues/detail?id=235884

+    [RaisesException] MIDIInput getInput(short target);
+    [RaisesException] MIDIOutput getOutput(MIDIPort target);
+    [RaisesException] MIDIOutput getOutput(DOMString target);

Ditto.

+    [RaisesException] MIDIOutput getOutput(short target);
 
+    attribute EventListener onconnect;
     attribute EventListener ondisconnect;
