The recently-released Audio Programming Book contains remarkably clear
introductions to PortMIDI and PortAudio.

However, there's one (key!) thing I can't find: how to integrate the two,
meaning how to write a program that accepts real-time MIDI input and passes
NoteOn MIDI messages to the PortAudio callback -- so that sounds can be
produced.

I'd need some code example.

Many thanks.

That's a good exercise for the readers! Some tips: starting from the  
MIDI input + output example,
remove the MIDI output; add a portaudio output (callback-based); pass  
the MIDI message buffer
to the callback via the userdata object; consume the MIDI input  
immediately in the callback.
You can look at the VST plugin development chapter in the DVD for an  
example of a synthesiser
code to do this last step (it's the VSTi example).

Thanks very much Victor

Just checking: are you talking about section 3.1 "MIDI Events", of DVD
Chapter 9, "More VST Plug-ins"?

This chapter doesn't seem to be mentioning PortAudio.

Samuel

yes, it's that chapter. I meant you can use the synth code from the  
VSTi in your portaudio-based code.
