I'm wondering how to do a seamless loop of my ringtones. I understand that this is controlled by each phone. An SP-MIDI file has MIP message and Program Change messages at the top of the file which create a delay when notes are there too. Therefore Nokia reccommends that you start your notes about a 16th note or so after the MIP and other setup events. Am I therefore correct in assuming that it is not possible to have a polyphonic tone which loops seamlessly to a point (eg. 16th note)after the start point?
