Polyphonic Audio to MIDI VST converter (free would be best!)

Hey Gang, Anybody know of a VST plug that converts polyphonic audio to MIDI? Any freebies that you know about? Have you used them? Worth a darn? I have seen the ads for the Widisoft converter. Not sure I want to spend that much on a plug I may never use again. If you have used it, I'd love to get your feedback. Worth it to you? Just to be clear... I have several audio tracks that were recorded using the audio output of standard keyboard based synths. The files are in standard wav format as recorded by Reaper. Like a damn fool, I forgot to record the MIDI info from the synths at the same time. I'd like to go back and use the audio tracks as the source, run 'em through a VST plug and output a MIDI stream reflecting the audio information. I'm OK with using an external program if necessary, but a plugin is more desirable. Thanks! ted

none have i found have even been worth free

There's Melodyne DNA, but it's far from free.

Rephrase (Leapfrog Audio) does monophonic audio to MIDI very well. It is the only one of the several I have tried that will do voice to MIDI well. I know of none, other than Melodyne with DNA (should be out in Sept.), that will do a good job with polyphonic audio. PS voice to MIDI track FX chain: ReaGate (remove LF background noise) -> Melodyne (for Pitch Correction and Quantizing Time plus any 'blob' editing) -> Rephrase (produces MIDI file).

audioscore from sibelius 6? anyone tried that for monophonic input?

audioscore sounds very promising. But no Vista x64 MIDI driver which is a show stopper for me and for many more Windows users who are switching to x64. I wonder if their MIDI driver must be used?

Hi, I'm also searching for polyphonic converter. There are some hardwares - or AXON (seems tb phased out). As for VST - there is only one plugin working properly - Pitch a Bitch from but it is monophonic. I tried WIDIsoft demo, but it is not working good. Honestly, I've got some bullshit on output.

That user pitch a bitch guy has been on a spam spree the past 2 days. I did however demo it, not bad but not worth actual money.
