I'd recommend checking out the post I made on page 3 with the picture. That should hopefully explain things.


Also
I tested automation delay compensation and it seems that is not fixed either.

I tried it with EQ8 and Auto-filter and I didn't see any delay. I guess it's just with third party plugins.
I also tried it with some other third-party plugins to rule out the possibility that it was a fabfilter issue but it behaved the same.

As you can see in the image above I loaded a kickdrum into simpler with the following effects chain:
Simpler > Pro-Q > Pro-C > VolumeShaper

As you can see the kick is delayed in VolumeShaper because Live is not compensating for the delay caused by Pro-Q and Pro-C and the kickdrum will shift back and forth in VolumeShaper if I add or remove plugins in the fx chain.

I am incredibly disappointed Ableton. Seriously, wtf.

2003

Cubase SX2.0 was hailed by many as a huge leap in functionality. One of the most innovative features was called Timewarp. This allowed users to record music either as MIDI and/or Audio in freetime, without click or metronome, and then move the bars and beats grid to the music, automatically creating a tempo track. The Timewarp tool actually allowed the user to move the gridlines.

Cubase SX2.0 also saw the introduction of Full PDC (plug-in delay compensation). Many plug-ins, particularly those which run on DSP Cards such as UAD-1 or Powercore, cannot process their audio within a 1-sample time period and therefore introduce extra latency into the system. Unchecked, this will cause some audio channels to end up out of sync with others. PDC checks all the various latencies introduced by such plug-ins and creates audio delay buffers to ensure that audio from all channels is correctly synchronized.

• make "automation" 1 beat up 1 beat down (filter on off switch will do it)
  add a few plugs
  listen to the "automation" being wrong every plug you add

• add a tempo sync plug (like noise gate or LFO filter set to square )
  add a few plugs after is ok
  add a few plugs BEFORE "tempo sync plug" is out of time
  listen to the "tempo sync plug" being wrong every plug you add
