I've asked for this type of utility a few times before. Qmidiroute and 
midirgui do some of what I've asked for but no stand-alone app does what 
the Yamaha MEP4 did, i.e., rechannelize, convert from one controller 
type to another, value scaling, event filtering, etc. It seems like 
these functions should be rather easy to add to an app like midirgui. I 
think most of the math is simple integer stuff.

Yes, Pd can do all this, but you have to have Pd on your machine. I love 
Pd, but unless it can generate a stand-alone application (that doesn't 
require Pd) then it isn't really meeting the need.

It's a shame Matthias stopped writing his MIDI utilities. I've tried to 
reach "holborn" (aka the author of midirgui) but had no success.

A software clone of the  MEP4 clone would be a very sweet MIDI utility. 
Perhaps a bounty would convince a developer to spend an afternoon 
writing such a tool ?

Best,
