Hi, I would like to report what I have found.

First, I had to remove the following lines from 'saturation~.model.presets.txt' inside /Users/km/Documents/Max7/Packages/Jamoma/patchers/models/audio/stereo/distortion/saturation

depth 10.000000 mode sinus preamp 0.000000

Otherwise, the values you save with a Live project file will not be properly recalled when opening it.

The remaining bug is: When opening a Live project file, the value of Preamp parameter becomes 0 visually and internally

When the Live project file is light, it does not occur. It sometimes happen (not always) when the Live project file is heavy.

I love the sound quality and CPU efficiency of Jamoma. It would be great to see the official amxd version with Jamoma 2 (perhaps as a paid Live pack).
