Midi not working_Pro Tools 12.7.1

[L-DAWG]

Hello Folks,

So I write to you today to see if someone can guide me through getting MIDI working again in PT 12.7.1 on my PC. I'm using a Korg Triton Extreme to transmit MIDI to my Focusrite Interface using standard MIDI cables. I've tried USB as well and still can't get signal to the DAW. However, when I run a standalone virtual instrument such as Waves Element App or Electric 88 App, the signal/midi works fine. I can hit the keys on the keyboard and everything is a - GO! But in Pro Tools, when I instantiate any virtual instrument and hit the keys, I get nothing.

I've gone through preferences and made all the adjustments needed on the MIDI tab; I've gone through MIDI Studio, and finally I've made the appropriate selections under MIDI Input Devices. Please Help and thanks in advance. I look forward to your guidance and assistance.
