Ableton does regularly update old effect devices or replaces them with new version.
I went back in installed older Live versions and saved presets to have access to these.

Here is a list of them:

Autofilter - opens new device, but keeps old settings
Compressor - all older features are still included, im missing Compressor version 1 and 2 from Live 6, which i cant save, since i cant find a working version. I use some older presets from the 6.0.18 installer. I am sure you can load them and save them in the settings you like.
Flanger and Phaser --> merged into Phaser-Flanger device, presets open this device, but use old settings.
Redux --> Redux 2 now, but Redux is still available with the preset.
Ping Pong delay and Simple Delay --> merged into Delay plugin, opens Delay plugin with old settings for both
Chorus --> new version with improvements, preset restores old features
Frequency Shifter --> new version with improvements, preset restores old features
Reverb --> new version with improvements, preset restores old features

new with version 12.1
Limiter --> new version with improvements, preset restores old features
Saturator --> new version with improvements, preset restores old features

New with version 12.2
Auto Filter --> New redesigned, but the old device still exists!

New with version 12.3
Auto-Pan --> Auto-Pan-Tremelo

it should be backwards compatible. thats what ableton wanted.

Any other devices Ableton updated? Did i miss some?

 

Auto Filter legacy preset added.

Ableton learned and kept the old devices in, but they are hidden and can only access if you use a project with the older version!
Or you load presets from here for example.

Enjoy.

 

v12.3. will arrive soon, it will replace Auto-Pan, with a new device. The Old Legacy still exists.

I have added the Auto-Pan preset to the pack already.
