When using the Audio Chord Wizard, is there a way to restrict the chords that will be shown as chords identified? Example: In the key of Eb, I only want the chords Eb, Fm, Gm, Ab, Bb, Cm & Ddim to be returned as chords identified.

I also do not see an option to process the song again after initially opening the Audio Chord wizard then opening the song that will be processed. Am I missing something?

I also do not see where I have any setup options for the processing of the song before the chord wizard does its magic. Everything seems to be automatic and built in to BIAB.

I am using BIAB 2016 with the latest patch.

tigeron,

Welcome to the neighborhood.

1:
I don't believe that the first item you mentioned is part of the ACW, however, you can certainly edit the chords at any time, changing them to your own selection once the ACW process has completed.

2:
I didn't exactly follow item 2. Can you explain your steps in more detail?

3:
There are options to fine tune the song after the ACW provides its initial pass, such as setting bar line locations etc. It does calculate a tempo map etc before. There are also settings for sensitivity, tempo quantize tolerance, etc. Check the Analysis drop-down menu.

Exactly what type of options were you looking for?

If I want to re-evaluate in the ACW, I hit play and tap the F8 key on the first bar of a few measures .. then the ACW looks everything over again. It re-evaluates the chords and bass root etc. on the fly.

Another trick is to either double or half the tempo .. again the ACW re-evaluates the song. But this affects how it is sent back to RB/BiaB (tempo), so use with caution.

I do not know of any way to restrict the chord options as you requested.
May be a cool improvement.

Or just manually change them for a section and copy/paste as needed.
I find I actually use it more to define a tempo map than the chords.. though the chords are usually 'close'.

Video Track, Rharv:
Thank you for your response. I just assumed that there would be some selections that you could choose from to help BIAB determine any constraints that you would wish to apply.

I do not know that much about music theory concerning all of the possible chord inversions and substitutions and other variations.

The result of the audio chord wizard seems to give back some complicated chord notations. Say for example it gives: Bbsus, Fm6, Eb7, E7B9. I was looking for something maybe more simple such as Bb, Fm, Eb. On the last one maybe a Eb or Bb would work. I am not sure what to do here. I was hoping that BIAB would allow me to restrict the results to just the basic notes in a key, which in this case is Eb.

If I knew what the chords should be then I could go in and just change them. But I am working to a unknown here.

What I am trying to do is get the chords to a song that has a very simple rhythm to it played on a Ukulele. On a pedal steel guitar we usually just use 3 picks to pick our chords.

The following is a link to a YouTube video. Right at the beginning there are a couple of strums on the Ukulele. Nothing fancy.

I bought BIAB last year and only installed it the other day, so there is a lot to learn.
Any help would be most appreciated.

As Bob says, F8 can be very powerful.

I wonder if Tigeron wants to reopen the ACW so he can do further edits on a song. I admit I hardly use ACW (I do transcriptions professionally) but I think he is correct that we can't do that, unless I missed something.

1. You can restrict the chords listed from the normal two chords per measure to one chord per measure from the Analysis drop down menu at the top tool bar.

2. I think Matt is correct that Tigeron wants to revisit the ACW editing process once he has imported the initial ACW edit and chord/tempo run. If this is the correct assumption, it is easily accomplished.

This is done by selecting the ACW button again from the Main page. A window will appear giving the option to either use the current song or to import a new song. Select the current song. You also have the option to choose between retaining the existing chord chart and just addressing tempo issues or redo the entire process. This can be done repeatedly if necessary.

Sometimes after import, the song is out of sync and the first bar does not begin on the first beat you selected. This is caused by the length of the opening silence before the first beat. The ACW could not interpret how many measures there are since it does not count in that space.

To correct this, open the Audio Editor. You will see a vertical line indicating where the first bar starts as determined by the ACW. Hit play, and you will see another vertical line that will move from left to right across the audio editor screen in time with the tempo. Right click on the Audio Editor screen and from the drop down menu select Mark this point as Bar 1 to manually set Bar 1 in its correct location. Then select Permanently set Bar 1.

This can be done repeatedly by setting the first bar, and playing a few measures of the song and if the location is incorrect, undo (ctrl-z) and repeat until the song begins correctly.
