How do i use the LCD Interconnection test?

Testing/Troubleshooting
1

My core module seems to be working via MIDI, i uploaded revision_id and it reported correctly that i had a 18F452.  However the LCD doesn’t work.  The first LCD i tried was one that i broke one of the tracks off while desoldering its previous connector and then tried to repair it.  I bought a second hand one to replace that but it only displays black bars, so i don’t know if it works or if i’ve damaged the output lines.

I’d like to use the LCD Interconnection test, but i don’t know how to send Modulation Wheel events.  I don’t have a keyboard with one and i only have Linux and Free-DOS on my computers so i can’t use MIDI-0x.  Does anyone have some MIDI files of Modulation Wheel events or a Linux program to send them?  I’d create them myself, but then i wouldn’t know if i’d written them wrong or my board really was broken.

You could send the modulation wheel event with the virtual keyboard of MIOS Studio

Here’s me showing my ignorance again, but how do i send a specific modulation wheel event with MIOS Studio?  I can move the wheel, but don’t seem to be able to just click a button to send a specific number.
