Could the MIDIpal be coded to do velocity remapping? Every controller has it’s own, and sometimes odd, velocity curve selection, or worse, no selection. I just bought an Alesis controller with less than ideal, for me, velocity curves, to downright bizarre curves. I would love to be able to take the linear mapping in the Alesis and remap it into what I want, and not let Alesis, or any other keyboard in my collection, dictate that velocity curve for me. Crazy idea? 
Could be your starter project to get into the MIDIpal codebase Very easy to do! There is only one handler to implement, the one for NoteOn messages.
Yeah, I suppose I could do that. I know what I want, maybe just a setting for min and max velocity, and a curve type to interpolate between min and max, pretty simple remapping you would think, I think that would get me where I want to go.
