Doepfer

Hello again!

Sorry to bother you all again...but I have another question.  
I have a A-112 sampler module and I want to trigger it from a Doepfer pitch ribbon (the pitch ribbon has the external R2M box).  The strange thing is that I can't seem to trigger the A-112 from the ribbon... I can trigger the A-112 from e.g. a LFO, and from the A-155 sequencer.  I am suspecting that the ribbon controller is delivering to low voltage (or that the A-112 wants slightly more "juice").  The strange thing is that the ribbon works fine with other modules...
Anyone with similar experience..?
Any good ideas...? Any simple way to adjust the A-112?

Thanks,

/Lars
