Defining keys on midi keyboard

I saw a topic on here some time ago about defining the lower keys on a midi keyboard to allow them to match the computer keyboard input for selecting note duration, accidentals, etc. But no matter what I use in my search, I can’t seem to find it. If anyone remembers that thread, could you please point me to it? I would greatly appreciate it. Thanks!
