UI/Midi Events

[drdream]

Hello I programmed a "Chord Helper" which helps users create chords and melodies locked into a Key.. It is in .Net Core/Blazor with view model for piano roll.. It already works well (except missing live piano roll like a DAW). I was looking to port this to VST for tighter integration with DAW.

In NPlug how would I listen and then forward midi messages? Also how to do UI?

Many thanks.
