I mean if I use the midi in and midi out of the m-audio 2x2m
Thank you in advance

If the Volca is fine and operational by itself, and the MPD32 is driving it successfully, then we know a few things:
Not the MIDI cable
Not the Volca's central electronics
Not the Volca's MIDI port
If the keyboard is the problem, but your computer recognises MIDI signals coming from it, then it may be a signal issue from the M-Audio keyboard.
For a variety of reasons, MIDI signals can actually operate on a range of voltages, and it's possible that the voltages coming from the M-Audio are just not good enough - this is why a powered MIDI-Thru box (such as one from Kenton) might work, by producing a better electrical signal.
Digression: a MIDI-Thru box such as the Kenton Thru-5 takes in one MIDI signal, and then multiplies it across a number of outbound MIDI ports. This lets you do things like have a sequencer produce data for multiple channels, and then have a number of Volcas all picking up the channel that is relevant to them. I use this to get multiple voices out of my Volcas and have my own Volca orchestra.
I don't know how much of an electrician you are, but if you have a multimeter, you can use it to figure out whether perhaps the M-Audio is sending low voltages that the Volca might not be reliably picking up.
It strikes me that it's also possible that the M-Audio is somehow not sending a useful Velocity value for each note signal, but I doubt it.
I hope that these thoughts help you.
