[CLAM] Play a note with MIDI

[Simonin Vincent]

I'm trying to run the MIDI_Synthesizer example but I have some problems. I first 
had some problems with the AudioIn objects and now I have this error message :

----------------------------------------------------------------------------------------------
Press enter to terminate
 AudioOut::ConcreteStart(): could not start audio device: maybe another program is blocking it
 Received error message: <ALSAAudioDevice::Start(): Failed to create PCM device.
 Nested error: SndPcm::SndPcm(...): Playback open error: Device or resource busy

About the developer who worked on the MIDI part of CLAM, I have understood that he's no more 
in the team. Is there a possibility to contact him ?

(just copying my answer at irc, in case it is useful to anybody else)

At this point all the documentation we have on this is on the source
code. You should look at the MIDI_Synthesizer_example.cxx
