Hi Alex,

Welcome to the forums.

Kelso is correct in that Band In A Box (BIAB): (a) can put chords to a MIDI melody but the chords would only be a starting place and would need tweaking; (b) cannot put chords to an audio melody with a great deal of accuracy other than using the Audio Chord Wizard.

Realband, on the other hand, might be able to help.

In Realband, it would be possible for you to record your voice only. It would be necessary to sing in time against a drum beat because, ultimately, if you want BIAB to harmonize the melody, it has to be synched to a tempo. To set this up, all that is needed is to load a style - a MIDI style would be easiest. Once the style is loaded, simply set the tempo and mute all instruments except the drums.

Once you've recorded your vocal, it could then be run through the option "Pitch to MIDI convert" (see image below, about halfway down the menu).



The Pitch To MIDI converter will attempt to convert your vocal to a MIDI melody. I suspect that the results would vary a great deal because aspects such as the sound of consonants and vowels could confuse the interpretation process.

If you do manage to get a successful MIDI file at the end of process, this MIDI could then be saved and read into BIAB. BIAB would then attempt to harmonize the notes with chords.

While the above sounds like it should be possible in theory, I anticipate that obtaining good results could be difficult. As I haven't tried it, though, I cannot say so with certainty.

Kind regards,
Noel
