I was taking a glance at www.vgmusic.com to see if "Let Me Know The Truth" was available, and it's not under DS; BUT... they do have a version under the original NES release of Final Fantasy III j.
Although, that midi is aggravating. There is note in there that's wrong, and I don't have my keyboard hooked up.. and because it weighs as much as my two dogs, and it's 2:45 in the morning I won't get it this very second; but I'm awful with notes and if I'm not looking or playing a keyboard I can't visualize what it is... but the midi is off I can guarentee that much, by one note in the harmony, and it happens every fourth measure if you're counting in 3/4.
Just thought I'd bring that up, if we can only locate that crummy midi.
