APC40 and MidiCC via Device control pot ?

[citric_acid]

Hi,

i ask me if i can use a pot of the device control section to control a midicc envelope.
If i want tu use a midi cc i can paint a envelope in the envelope menue / window.
but i didn´t find out to do that with a pot.
How can i do that? or can´t i do that ?

I saw some patches for max but this i used was buggy and it didn´t used the right pot on my apc.

Does any one has an idea ?

Thanks a lot.
