FluidSynth looks cool.  I had never even heard of it before today.

I have researched how to implement ringnote (feel free to suggest a 
better name! :)).  The QtEI GUI (in the Profile settings) does not 
appear to support running a command on incoming calls.  AFAICT, a QtEI 
client app is required:  see

<http://qtopia.net/doc/qtextended4.4/qphonecallmanager.html#newCall>

The client app has to use FluidSynth to play the MIDI notes 
corresponding to the digits in the calling phone number.  The client app 
(what should we call it?  ringnoteclient?)  could call an external 
command, such as a bash/Perl/Python script, or interface with FluidSynth 
directly.  Calling an external command would be more modular and maybe 
easier to maintain, but having ringnoteclient interface directly with 
FluidSynth may be simpler.

I have 2 problems, though:

1. I do not even have a development environment/toolchain for building 
ringnoteclient.  I know I could get one, but I am afraid I will be 
starting Yet Another™ underestimated project. :(

2. I have little experience with C++.  I could learn more as needed, but 
I still prefer C over C++.

So, can anyone with the required tools and C++ experience help? :)
