My understanding is that when using the object "midiout" or "noteout" you should see a virtual output option which can be routed to other applications. I only see Microsoft Synthesizer, Microsoft GS Wavetable Synth and my USB MIDI interface. I'm using MAX 6 and Windows 7 64-bit. I have looked through the max docs and in every dialog box I can find for a way to enable virtual MIDI. I assume this is some sort of OS setting I'm missing. Any help? Thanks.
