Logic Filtering AU generated Sysex?

I'm trying to send sysex messages via my audio unit plug-in, but Logic seems to filter it out (other hosts pass it along just fine). I tried midi plugin + external plugin, or au instrument connected to midi instrument.

is there any setting i can use in logic to prevent that from happening?
im trying to code a controller for my mks-80
