Dada and RD-8 Beringher

Hi there ! I tried to connect the Automat to the RD8 (Beringher drum machine) through the Automat Midi In.
It receives the Midi and the leds flash according to the drum machine patterns , but the solenoids are not activated.
Any idea to solve this ??
Thanks in advance, folks !

Is it powered?
Sounds like it should work

Yes it is powered : the power supply is well connected !

Did you press the learn button before sending the lowest note from the RD8?
