The 3595 can only play midi with 4-chords. And for you to do this you can use Anvil Studio to remove unecessary tracks and trim it down to 4 tracks or instruments. Then I tried to upload the modified midi but it still doesn't play. So what I did is use the Nokia PC Suite's Sound Converter and modified the polyphonic values of the tracks and upload the re-modified file to my phone. After doing so, you can hear the midi play perfectly.
