vst and NI Absynth

I want to integrate NI's Absynth in my patch using the vst~ object but I have some questions.When asking the parameters I get the following list:

print: Macro Control 1
print: Macro Control 2
print: Macro Control 3
print: Macro Control 4
print: Macro Control 5
print: Macro Control 6
print: Macro Control 7
print: Macro Control 8
print: Macro Control 9
print: Macro Control 1
print: Macro Control 1
print: Macro Control 1
print: Macro Control 1
print: Macro Control 1
print: Pan LR
print: Pan FB
print: Attack
print: Decay
print: Sustain
print: Release

As you can see, multiple Macro Control 1 so I do not know where that points to. Also, when sending a message I get an error message that the parameter Macro is unknown. The named parameters (like attack) seem to work fine.
So questions: what are the macro Controls? How do I deal with the multiples?
