You need to be able to send the midi out of VSTi's to another VSTi, at the moment you can only load a VST FX after a VSTi.
With IL MiniHost vsti/vst now you can.
Like RapidComposer, RealGuitar and other VSTi's you can send the midi out to a VST Instrument like Kontakt.

Join the FL Studio Forum and download free MiniHost Win or Mac

Load IL Minihost Modular.dll on an instrument track (IL Minihost Modular.dll (Fx) for Audio Tracks)

Open plugin - File - Preferences, add vst folders and scan.
Right click on screen - Add Plugin

In The pic below midi is coming into RapidComposer - midi is going out into Kontakt - audio out of Kontact to audio output.
