I think @persist maybe referring to a modification of the Midi Maestro, which has even noisier switches than Aeros. But I don’t know whether this would work with Aeros as well, apart from the fact that you will ruin your warranty.
Another solution would be an external midi controller. But for acoustic recordings I would strongly advise against the Midi Maestro. You could look after something like the Nektar Pacer, Behringer FCB1010, Keith McMillan Soft Step, iRig BlueBoard or something similar.
