MIDI Control of Mesa Dual Recto

[protoplasma]

On the back of my recto there are multiple discrete inputs for switching channels, fx loop, and solo. Does anyone know of a simple device that generates switch closures via MIDI commands? I've thought about building something simple to do this if nothing is out there. Perhaps there is a small market for an inexpensive MIDI switch closure interface?

there are some options, but none of them i have found are cheap. gcx and rjm switcher will both do that.
