Fix "Sour" Notes
Out-of-tune notes in RealTracks will be auto corrected to match chord tones. This fixes notes that are outside of a desired chord or scale by pitch shifting them. For example, a G# will be pitch corrected down to a G if the current chord is CMaj7. This feature can be used for editing specific regions of an audio track, or it can be applied as a track setting that will automatically pitch correct RealTracks when they are generated.

For the Audio track, highlight the region you want to fix in the Audio Edit window, click on the [Edit] button, and select Fix “Sour” Notes from the menu. Then, when the dialog opens, select the rule to apply for the pitch correction.

For the RealTracks, right-click on the track radio button on the main screen, go to Track Settings - Auto Fix “Sour” Notes, and select the rule to apply for the automatic pitch correction. For example, if Song Chords is selected, a G# note played on a CMaj7 chord (C, E, G, B) will be pitch shifted to a G note. Choose Specific Parameters opens the dialog that describes each rule and allows you customize the rules.

Process MIDI: If this option is enabled, any MIDI on the track will be processes as well. Notes within the selected region will be changed according to the chosen rule.

It's suppose to with Midi but I couldn't get it to work.


If you have Reaper, items can be dragged out of Reaper and dropped directly into Biab.
