Pyramid incompatible with M-Audio?

I have the same problem with my Moog Grandmother. Pyramid is not accepting the MIDI Data from that device. But Grandmother can communicate with any other usual device without a flaw.
I think there is a bug in the PyraOS 3.1.
Contact Squarp directely and tell them of this specific incompatibility: Contact us | Squarp instruments
Myabe it helps (I wrote too).
