In a recent video I showed a method to convert Midi Notes into Helix CC values to be used by the 3 note generator by both midi controller and guitar (+Midi Guitar 2).
This video goes over a stand alone application I created that can be used in place of the DAW configuration.
This is meant to work with a pre-configured preset on the custom tone that already has the MIDI CC values set up for you: https://line6.com/customtone/tone/591...
The stand alone plugin can be downloaded here:

Note, I am quite new to plugin development, so feel free to let me know if this doesn't work for you.
Here's a drawing of how to use it with a midi controller:

Also, the reason that this is a standalone application as opposed to a VST2 or VST3, is because VST2 support is ending. VST2 would have worked fine, unfortunately. I would target a VST3 plugin, but VST3 plugins do not support creating and sending Midi CC messages without some hacks? If you want to go down that rabbit hole (https://forum.juce.com/t/midi-cc-mess...)

Correction: 1:39 This is using the "old" image background. I wanted to convey "CC", but it looked more like a typo than anything.
