Some s40 devices do not play midi files with 16 voices.
The features of those phones show compatibility with this format but phones display the following errors “wrong file format” and “file is corrupted”.
I’ve tried to solve this problem in many ways but, unfortunately, without success.
Phones play Midi only with 13 voices maximum. The same thing happens with SP-Midi.
Midi 16 works correctly only on 6030 headset, and do not work on the following headsets: 6020, 6021, 6610i, 7260.
