Monophonic ringtone conversion

[ghost]

I got to feeling nostalgic the other day, so I tried bringing an old monophonic Nokia ringtone to my smartphone.
I found your RTTTL converter quite helpful, but the synthesized beeps just don't sound authentic enough to my ears.
I did some more research and came across Ed Ball's monophonic ringtone synthesizer that sounds more like my old Nokia phone (Live Demo: http://outputchannel.com/monophonic-ringtone-synthesizer , Source Code: https://github.com/edwardball/monophonic-ringtone-synthesizer).
Would it be possible to somehow combine these two projects to get the original Nokia sound out of a *.rtttl / *.mid file?
