Audio to midi

I want convert an audio track (old recording of bass) in a midi track. Do you know a good soft (or plug) able to do this ? Thank you for help.

Or use Jam Origin MIDI bass, especially designed for this instrument :M there is a demo on the we site. Fregle solution is surely less expensive.

Thank you for your help, I'll try these solutions ;)

OK. Reatune doesn't make a good job. I must work and work again to clean the midi track. I work fastest with my ears and the midi editor.;)

Melodyne Editor will take a WAV file and convert it into MIDI, if you want. I suspect other editors will as well, if you search (google) a bit. You said, "I want convert an audio track (old recording of bass) in a midi track." You meant "into" instead of "in", or maybe I'm misunderstanding your goal?

My english langage is poor. In or into ?

Jam midi guitar. Try pitching your bass track an octave up/ or cutting bass frequencies with hipass filter. For electric guitar Jam product is the best without any competition.
