evn i've not heard about that. theres couple of wav to midi converters n vice versa on the wave. may try these. thanks. (anyway, u may look for on www.planetddl.com..... yeah freeware obvioulsly)
no such thing. there have been some software that tried it years ago, but they were wildly inaccurate and abandoned eventually. if it was a single instrument playing single notes, it would perhaps be feasible, but anything beyond that is... well, impossible. midi doesn't work that way.
