Question: how can a song could be converted in midi format? i have some some songs in my pc, and i want them to be converted from mp3/wma format to midi format, just as we can converted from one to another format. i've tested several conversion softwares, but no one meets my requirements

Answer: It's not inherently doable because MIDI is a format for synthesizing musical instruments, not digital audio.  Any software that claims it can do so is yanking your chain.
