Ah, sounds about right. I believe Walking In My Shoes' distorted harpsichord/piano set utilises parameters controlled by velocity in some way, which might be what's giving EMXP that error message.
That would be a great feature, would simplify issues like these so well.
Thank you, that would be wonderful, I'll upload a copy of the bank image for you right now. Ironically enough, I'm expecting a refurbished EMAX II with a new power supply to be delivered sometime this coming Monday, (although I don't have physical copies of the banks on floppy disk, unfortunately, will have to look into writing the .EB2s to disk at some point soon).
Here's a copy of the .EB2:
