How can I activate a custom PCM_sink for MIDI?

Hi all,

I've recently implemented a PCM_sink for recording audio (WriteDoubles gets continuously called). This PCM_sink can be activated for new recordings by the user in the project settings ("Audio format for new recordings"). Now I want to write a PCM_sink for recording MIDI (WriteMIDI will be continuously called). But is it even possible to activate PCM_sinks for MIDI recordings? I haven't found any way so far :(

Any ideas?

Thanks
Ben
