I am currently trying to create polyphonic ringtones for the Nokia 3510.
I say trying because I have run into an unexplainable problem. For apparently no reason some the the ringtones I have created fail to play on the 3510. I can download them, but, when I try to play them the phone reports "Unable to Open File".
This seems to be a sporadic problem with no pattern of cause. Here's what I do know so far:-
- File size is irrelevant ( the problem occurs in files as small as 2k and as large as 10k)
- Instruments have a little effect (all ringtones use only instruments from the Introduction to midi doc. but sometimes changing an instrument will make a file work)
Also this problem occurs in different files with completely different sets of instruments - so it's not a problem with one specific instrument.
- Complexity has a little to do with it. Sometimes removing one unnecessary track will fix the problem
Can anyone help me solve this problem. I have experienced the same issue with both the 3510 and 7210 - so is this a Nokia compatibility issue? All other handsets- Samsungs, Motorola etc work fine.
Any help is appreciated
