I am going to assume that you are talking about audio to MIDI, thus you will need either hardware or software like the following:

Software:

Or this http://audio-to-midi-vst.en.softonic.com/
I do not have any experience with either of this. Also google/bing audio to MIDI and you will find a number of other software programs that do this. The best audio to MIDI program I have come across is Melodyne Editor http://www.celemony.com/cms/index.php?id=editor2

Hardware:

Again google/bing for others just remember good audio to MIDI software and hardware is expensive.


I think my wife has started to show the first signs of dementia.
She said she can't remember what she ever saw in me!

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
