TLDR: I do not think that the MT Powerkit 2 Drum VST generates any MIDI when its drum pads are clicked. If so, there is no MIDI to record. You will need to record the MIDI from your Roland or from Reaper's VMK.

Understood. To find out if the plug-in generates MIDI:
-- create a new track.
-- add the plug-in and the JS FX "midi_logger" to the track, in that order
-- click the plug-in's GUI (on drum pads etc)
Do you see any MIDI notes in the Logger
If not then the plug-in does NOT generate any MIDI.

Here is one that does (son't worry that it sends two Note Offs for each hit, that is by design)

OK, but they are Inputs to the track. That is different from any MIDI generated by a plug-in, which is seen as an Output from the track. Hence the two different menus choices for recording the MIDI.

I'll do my best. see above.

NO, it is the virtual instruments which convert MIDI data into audio.

Let's take the cases of playing the virtual instrument with your Roland keyboard. You have selected its MIDI as the Input to the track. So, the only input that can be recorded is the MIDI from the keyboard.

Now, that virtual instrument will convert the MIDI data into audio (and it may or may not output MIDI. So, if you switch to "Record Output (mono)" or "Record Output (stereo)" you can record the audio created by the plug-in. And, if you switch to "Record Output (MIDI)" you can record any MIDI created by the plug-in.

Would that have anything to do with all of this?
That option is used when you wish to use the MIDI Device to send control messages to automate things in Reaper. That is not relevant here.
