Anyone know if it is possible to use MIDI files as ringtones on 9210?
Or is the only way to convert to WAV.

Asking as I know a great site with lots of Midi files.

Or if there is a program that will play them, even if not use as ringtones!

I've not actually used it myself, but you could take a look at RingMaster from http://www.zenobyte.com/ringmaster/ which has on its feature set list Import simple MIDI ring tone files

All the best

u cant use midi ring tone at your 9210 but u can convert it if u have ringmaster
