Keystroke to midi utility?

["Michael Stauffer" <michael@circular-logic.com>]

Hi,

I remember hearing (I think on this list) about a small utility program
that will generate midi events from computer keyboard keystrokes.
Something that sits in the background and intercepts designated
keystrokes and, allows your main apps to be in foreground and accepting
other keystrokes. I've looked in the archive and couldn't find anything.
Does that sound familiar to anyone?

Thanks,
Michael
