Clip Automation

Producer Pal can read and write automation on your clips: mixer volume, pan and sends, and device parameters. Ask for it in plain words, like "fade the pad in over the first four bars".

It needs the remote script. Writing automation also needs Live 12.4 or later. On Live 12.3, reading and clearing still work.

Session Clips

A session clip holds its own automation (clip envelopes). Producer Pal can read it, write it, and clear it, and it travels with the clip when you duplicate it.

A read tells you when an unwarped audio clip's envelopes won't play, and when a clip has envelopes Producer Pal can't see (modulation, Gain, or MIDI CC).

Arrangement Clips

You can write automation on arrangement clips too. In the Arrangement, automation belongs to the track, not the clip, so Producer Pal writes the track's automation lane over exactly the span of the clip. A few things follow:

• It can't read the points back or clear it. Live's API doesn't show a track's arrangement automation (Producer Pal can tell which parameters have a lane). To change it, write it again: that overwrites the lane over the clip's span. After the clip ends, the lane returns to its old value.
• The automation stays on the track. If you move the clip, the automation stays where it was. Automate the arrangement last, once the clips stop moving.
• The clip gets a new ID. The clip itself (notes, audio, settings) is kept.

Copying an automated session clip into the Arrangement also writes its automation onto the track, over the copy's span. For each parameter the clip automates, that replaces what the lane held there. Other parameters' lanes, and the lane outside the span, are kept. A copy longer than the clip loops its automation, as playback would.

Overridden automation

If you move a parameter by hand, or ask for a new value on a parameter that has arrangement automation, Live ignores the whole lane until you press Re-Enable Automation. Producer Pal says so when its write does this. Writing a new envelope re-enables the parameter's automation for you.

Try Asking

• "Read the automation on the clip in track 2, scene 1."
• "Fade the volume of the pad clip in over the first four bars."
• "Sweep the Auto Filter's frequency on the bass clip up across all eight bars."
• "Pan the hi-hat clip slowly from left to right."
• "Add a send 1 swell on the last bar of the vocal clip."
• "Clear the volume automation on that session clip."

How It's Written

For the curious: the AI writes each automation line as a parameter plus a list of points, using the same bar|beat positions as notes. Points are joined by:

Joiner	Meaning
/	straight ramp to the next point
_	hold the value, then jump at the next point
~N	curved ramp, N from -1 to 1: above the straight line when positive, below when negative

For example, 1|1 0 / 3|1 0.8 _ 4|1 0.2 ~0.5 5|1 1 ramps from 0 to 0.8 over two bars, holds it until bar 4, jumps to 0.2, then curves up to 1 at bar 5.

• Values are raw, usually 0 to 1, not the units Live shows (a filter in Hz, a percentage). Mixer volume 0.85 is 0 dB. Pan runs from -1 (hard left) to 1 (hard right).
• Each line replaces that parameter's whole envelope. On a session clip, an empty line clears it.
• On an arrangement clip, bar 1 is where the clip starts. The points run once across the clip, however it loops.
• Session audio clips must be warped. An unwarped audio clip can't play envelopes, so writing one is refused until warping is on. Arrangement clips don't need it, since their automation is on the track.

The tool settings are include: ["envelopes"] on Read Clip and envelopes on Update Clip. Reading envelopes works on session clips only.
