I had a bunch of ants in my Focusrite scarlet a few years back. I put it out in the sun, and that killed them off. Probably not good for the MPC. I do the opposite with my sugar jar (one of the lids doesn't seal right and I use for my coffee jar, but sometime they get switched), so I put it in the fridge for a while, then scoop them out. You could try putting the MPC in a sealed bag and in the fridge.
Ant's are a major head ache here, so I picked up some Japanese ant killer.

Works on all ants, not just Japanese ants
But a friend of mine gave me Vietnamese ant killer, And I refill that with 2 drops that in the old Japanese ant killer boxes to keep is safe from my cats.

They both work the same way by being taken back to the colonony and killing the queen and lavae. By the next day they are generally gone. When I get more ants again, they are a different species, sop it starts again.
In the UK, we only have a few types in the house, in VN, we get loads of different types, some are hard to see, some massive, and some super fast with long legs.
