If I export midi tracks from Biab, the quantizing is not really great. If there are correct showing notes in Notation view, it should be possible to create exact midi files.
I'm not sure if I am completely following, but currently BiaB tempo values are restricted to whole values (123 bpm, 124 bpm etc).
If you imported that into a MIDI song with a different absolute tempo setting (e.g. 123.5 bpm), then you would experience a quantizing issue.

If I create a 120 bpm midi track and export it to my daw at 120 bpm. If I analyze it, none of the notes snap to grid. They are all a little bit late or early, or to short. If I select those notes, I get values like 13/32 or 0.05 length. I do not have any 1/4, 1/8, etc notes.
OK, That sounds familar. Could it be this?? The default here is 40, I always need to set to zero.
Otherwise, depends on how the midi is made. Perhaps this midi is not quantized and is transcribed? or is real midi played by artist? What is the source of the midi (style)?
Just checking, when you say you tried the highest PPQ, you changed from 120 to 960, yes? Actually, I think that would be counter productive here. It doesn't go lower that 120, the default, but does that help or hurt?
In newer versions of BIAB, look at Edit, Slide Tracks. In older versions, it was under the Play menu. Are the checkboxes checked for slides and humanize? Turn those off.
Audiotrack already mentioned, your BIAB tempo is limited to an integer. However, in porting BIAB files to a pro studio, I have found that precision isn't always there. In other words, a rendered file at the tempo of 120 might come into a pro studio at 119.87; something like that. I don't know a workaround for that unless the DAW software has a snap function.

I changed the amount of ticks from 40 to 0. That improved the chord output. Because they were also off. Tried several settings, but the melody is not quantized.
Not sure if this influences midi length, but I can't hear the difference. I am not that good. I can only see it. Quantize in my daw afterwards is complicated. Some straight songs have triplets. I can choose with option, but not both.
I think this is a build in humanize thing. Because I do believe Biab is not capable of creating 1/4 notes if it is a 1/4 note.

Tried highest PPQ.
Or am I missing something.
Yeah. What you're missing is that real musicians don't snap everything right to the grid.

MIDI is as mechanical as it gets and it should be perfectly aligned unless there is something at work he we do not yet understand. I wonder about this if it is something PG Music should see.

I was under the impression that BIAB aimed at creating more or less realistic parts.

Byron, Yes, and that’s why it has settings. I have always assumed if you turn off any ‘humanize’ settings, you’ll get mechanical precision. But perhaps that’s wrong.
Leo, there may be settings in the style that cause this, and that would be intentional.

Found more info. I think it is not an error, but humanize is integrated. I had a look at Melody > Edit melody track > Step edit melody. From a song created by the Melodist.
The starting points are on different clicks and the durations also varies. So it is done on purpose and this explains the variations in the midi. Correct me if I am wrong.
Very good. I don’t use the Melodist so I will defer to others.
He's talking here about the Melody track, which I can see from the manual can be quantized or not (along with Soloist.)
What about regular band tracks? I do not see quantization as an option for them. Should they export to MIDI perfectly aligned or not? My guess is that they might, sometimes, but that one absolutely cannot count on that.
My testing shows timing that varies "humanly", as is visible in Logic's piano roll but NOT its score editor.
It might help if someone else tried this. I am not using Melodist or any fancy stuff, just basic style bands.
OK. He said this: "From a song created by the Melodist" so that was the basis for my comment.
