Nokia 6610 ringtones

The 6610 takes midi files of polyphony level 4, sizes of around 10 kb
and less, and with instruments the phone can recognise.

The easiest way to convert a midi file to play on the phone is to use
PolyPhonix, the only software written specifically with Nokia phones
in mind, allowing you to connect directly with the phone and use the
inbuilt phone profiles of the software for the instant editing of the
files to match your model. I find it great- especially as I use the
vibration of my phone as an instrument! Check it out at
