Playing multiple VSTi for Synth Layering

[FreezeFlame(Alchemy)]

Been trying to figure out how to do some synth layering using MIDI in OpenMPT, and so far, i failed.
My intention is to use a MIDI keyboard to control VSTi's mapped at channel 2, and have them played at the same time.
This is to create new types of sounds and being able to play them on the keyboard.

Would anyone mind pointing out how to setup OpenMPT to play VSTi using MIDI channels controller by a MIDI keyboard, without the need to write notes to the patterns?

Since there is no way to split audio or MIDI signals at the moment, you either have to copy-paste the pattern channels, or restrict yourself to VSTis that offer MIDI thru (most of them don't) so that you can chain them.

Thank you for the reply. Am sticking for now on "copy-paste the pattern channel".

Out of curiosity, what would be required, from your point of view, to split the audio and MIDI data streams?

A sensible UI that is easy to understand but currently doesn't fit in the space that is dedicated to the plugin section on both the general tab and instrument tab.
