Anyone know any good mp3 to midi converters, that are free? I don't care if it is terrible quality, I just need it to do the job with any mp3. I've tried audacity, and it doesn't convert it to midi, it doesn't let me. It just says it is invalid. Widi did the job correctly, and it sounded pretty good as well. The only problem, is widi only converts 10 seconds because it is the demo. I'd just like something simple that is free, not looking for anything big or professional.
