Ableton Forum

Hello, I use ableton live 12 to make mixes such as below:

Does anyone know how I can extract start/end times for each audio file, marker, or track?
I want to generate a timestamped tracklist like so:
```
00:00 エクソシスト = "The Exorcist"
03:23 天使のささやき = When Will I See You Again
06:31 私の孤独 = Ma Solitude
09:49 愛のためいき = Feel Like Makin' Love
14:23 バクスターのテーマ = Theme From "Baxter"
17:24 イッツ・トゥ・レイト = It's Too Late
20:31 愛は夢の中に = I Wan't Last A Day Without You
```
I've tried to write code that does this in both Python and Javacsript, but the furthest I get is being able to convert the .als file to an .xml file, but that xml content does not contain this info to my knowledge. Does this data exist anywhere? Or should I write a VST mod to do so?

Below is a sample of what the .als .xml content I'm parsing looks like, and here is the full file:

Using "API Browser.amxd" from Building Max Devices Pack I went through Live's structure until the start_time parameter (live_set tracks 0 arrangement_clips 0 start_time) of a single Clip placed at the 4th bar in Track 1 in Arrangement View.

It showed a "16." value.

I dragged the Clip forward out of grid a bit, then it showed "16.509883".

So I believe Live uses the Beat (at 4/4) subdivision as the time unit, "16." was for Clip exactly at the 4th Bar, "16.509883" literally a fraction after 4th bar.

Furthermore there is a "end_time" parameter, but the "length" parameter seems to refer to the original length before any looping or warping, so I think you would need to subtract start_time from end_time to get the length (in beats).

Then you would have to calculate using current BPM to get beat length in ms or seconds.

https://tuneform.com/tools/time-tempo-b ... seconds-ms
https://www.omnicalculator.com/other/bpm
https://toolstud.io/music/song-length.php

For example, 1 beat at 120 BPM is 0.5 seconds. so 4 bars would be 8 seconds, etc.

(I have absolutely no idea how to calculate if there are tempo changes.)

Regarding XML format, I think "CurrentStart Value" is a Clip's start_time, and "CurrentEnd Value" is the end_time equivalent.

So (from your copypasted XML data) the "Come Get it' - Psychostrumental 1990 a LaRhon Recording - eLBee BaD The Prince Of Dance" Clip starts at beat 0 (right at the start 1.1.1) and ends at beat 876.53655329045955.

876.53655329045955 - 0 is still 876.53655329045955. obviously.

At 120 BPM, 876.3655329045955 × 0.5 = 438.268276645229775 seconds, divided by 60, 7.30447127742049625 minutes long.

(Googling shows that Come Get it song is about 5.15 min long, so I guess it has a higher BPM than 120).

EDIT: Locators are "cue_points" in LOM, right under live_set (like "live_set cue_points 0") with a time property, in the XML they are simply named Locators (<Locators> </Locators>) with a Time Value property (like "<Time Value="64" /" >, again, in 4/4 beats.
