I think you will get better support asking this in the off-topic forum or maybe the PowerTracks forum. This forum is for people to post tips and tricks on how to accomplish different tasks; not to ask for the tips and tricks based on a problem. Ask in the other forums and folks will be happy to jump in and help you.

That being said, it is very difficult to render WAV to MIDI. You might have some luck with a single instrument track, played straight, and in tune. WAV is the resulting audio file format from the different audio sources used to create your song (for example, MIDI instruments rendered to audio sound, your voice recorded from a microphone, your guitar playing recorded directly from the amp), usually all blended together to form what you hear on the radio, or on a CD, or on your iPod (MP3/WMA is just a variation on WAV for all intents and purposes).

MIDI is (at it most basic) just commands to a MIDI sound capable system (such as your sound card or external MIDI module) to play a note pitch for some length of time at some volume (0-127)using some specified instrument on this channel (1-16). Yes there's more to it, but that's the basics.

A wav file is sort of like baking a cake. You add all the ingredients (MIDI commands along with other audio sources) and you end up with a tasty cake (nice song that you can listen to). Trying to create a MIDI file from the WAV file is sort of like trying to separate out the flour, eggs, milk, nuts, etc from an already baked cake. I'm sure through some level of chemistry and physics, you can get some of it, but you're not really going to be very succesful. Getting the MIDI from a WAV file (again, except for maybe a simple single-melody, single-instrument source) is going to be just about as difficult.

PowerTracks will try to do it with a single melody/instrument source (there's a command in PTPA for that) and the ACW (Audio Chord Wizard) will extract chord information, but it's not 100% and more tweaking is generally required.

Probably not the answer you want to hear, but it's been asked hundreds of times before and the answer is still the same.

That's not to say that as computers get faster and the software gets smarter, that we won't get there one day. The technology just isn't there right now.
