Hey Mike, thank you so much for taking the time! I will check if I'll get more reliable results with you method, but for now I'm still confused. I went through this tutorial:
There it is mentioned:
"We can enable the saving of pattr preset data in your Live set rather than writing and reading preset data from an external data file by setting a single attribute.
If you’re a regular user of Max accustomed to using the pattr family of objects, you’re no doubt accustomed to saving pattr presets as a part of your patch by setting the autorestore and savemode parameters. Many users include those attributes as arguments to the pattrstorage object using the standard at-sign syntax (e.g.pattrstorage my-presets @savemode 0 @autorestore 0).
In Max for Live, you can achieve the same result by enabling the Parameter Mode Enable attribute.
Select the pattrstorage object and open its Inspector. Locate the Parameter Mode Enable attribute and click in its checkbox to enable the parameter. When you do, you’ll see a new group of attributes appear in your Inspector. These new attributes are all unique to the use of the pattr objects with Max for Live.
Note: You’ll notice that when you click on the checkbox to set Parameter Mode Enable, the savemode and autorestore attributes will be greyed out when displayed. You may also notice that the values for the greyed out parameters are set to values of 1 rather than 0. The displayed values represent the default value of the attribute before it was disabled – the behavior of the pattrstorage object will be precisely as though you had set both attribute values to 0."
In addition to that, if you open the pattrstorage Help, go to the Max for Live tab and check the settings of the pattrstorage object it's just like my settings. It really looks like there is something broken with Parameter Mode, at least in my setup (Windows 8, Live 9.0.6, Max 6.1.3, everything 64bit). Can someone confirm this?
PS: Below you find my test patch to make testing easier. It has to be noted that something IS saved with the set, but what is reloaded is a mess.
Edit: I just realised that there was a silent update after I installed Max (I was on "Version 6.1.3 (c65b953)") and in another desparate try I uninstalled Max, downloaded Max61_x64_130708_ac9dafd.exe and installed it: it's still a mess. I also tried to set all the buttons to Hidden instead of Automated and Stored, because I thought there might be a conflict between the button storage and the pattrstorage: but the mess when reloading a set goes on...
