SOLVED!! It turns out that my MIDI-Keyboard-Controller, the Roland-A-800PRO, had somehow gotten tangled up in its own shoelaces. I started troubleshooting by attempting to connect a different Keyboard-Controller and when the problem disappeared completely, I knew that the A-800PRO was the issue. This Keyboard is hard to understand and I finally just unplugged my USB connector and re-plugged it. The A-800PRO then reset itself and now everything is back to normal.

Thank you for your time.
