for my girl's treo 600. she has downloaded some MIDI ringtones but volume is low and she wants them louder. volume of the ringer is at it's max and sound is still low. i tried MIDI Fixer off the net but doesn't seem to raise the volume to a noticeable level.

 

I have used AnvilStudio to up the volume and edit midi's for ringtones

Get it at: http://www.anvilstudio.com/

 

i use it too, a little clitchy but it works okay

my favorite option is the "truncate(from start to position or position to end)" option, that way i can take MIDIs of full songs and edit them to what part of the song i want to be the ring tone
