I'm trying to turn mp3, wav, or sdat files into MIDI. I have explored several programs, like VGMtrans, Amazing MIDI and WIDI (which, while working perfectly, cost £170 ) but none of them have worked. I can get the particular music in .NDS, .mp3, .wav, and .sdat. I understand that a regular sound file to MIDI is a big leap, and I would really appreciate any help. I know that MIDIs can be ripped from .GBA files, so I know it can be done.
