We also had the Idea but I never worked on it. The idea came from a
Friend (Marlon) after I explained him how this program worked:


His idea was that you can generate some musical tone after a phone
number. His idea was not to have a direct mapping from the number to
some kind of music but to map the calling number to unique melody that
you could learn to map to persons with time (I guess you would learn
the numbers that call you often rather  fast).

This is a nice approach because from the number you could:

- Select an instrument from a pool
- Select the timings
- And the melody

I used songwrite because it was easier for me to generate notes this
way. But I guess that generating a midi is the right way to go.

Not for ringtones but I've used LAME also to encode the files I
generated (-h -V2 -b32 -mj -q1
