Good Idea, thank you. I used MIDI-Ox and MIDI Yoke to see what the plugin outputs.
All the knobs and buttons are programmable, and after setting up, I realised, that the the VST outputs/passes through everything, when the internal "MIDI Output" function is enabled (this was implemented as a not fulklky suported feature though...): The notes, and the knob/button movement. This is the good news so far. Bad news is, the isn't any dynamic output, when "next step" for example is pressed. So my initial Idea would fail.
I DID a forum search, but as I see now used the wrong keywords maybe. As my first thoughts now failed (see above), I will take a closer look to your posts there, to see wether I could use this. Thank you!
OK, I read this through without looking at all this code. It seems that this woul near the solution to my needs, but no treach it, because this requeires either messages from the VST Plugin, or rewriting the whole sequencer into the LED processing code...wich might be not so easy, as I know only very basic things about programming and no experience in C.
So at the moment this all looks like I can give up my idea unless I get into this programming stuff?!
