Clarification needed: How can you work with midi (events) in Cubase with VST3?

Hi, i’ve really tried to do the research, but I can’t get definitive answers as to what is possible with cubase 14 and vst3. Midi plugins and editors can’t be customised, as I understand it.

What i want to do: Create a vst3 plugin that works on a selected midi part (in Cubase), and which updates the midi part - that is the function of a custom midi editor as an alternative to key/list/score. Thus, the vst would need the full eventlist for the part, and then be able to return the full event list to update the part.

  • Is this at all possible?
  • How would you use this plugin with a midi part (specific menus, insert points, etc?)
  • Do you see a better route to create a custom midi editor inside (or “inside”) cubase (and other daws by extension)?

Thank you!

Hi,
I’m afraid this is not possible with VST 3.
VST is mainly a “realtime” API which operates on short blocks of data and is not intended to work on tracks/parts.

Cheers,
Arne
