I use Cakewalk Sonar and am not familiar with Logic's MIDI routing or VSTi hosting architecture but here's how it works for Sonar:
Sonar does not have MIDI 'sends' or 'patch points' so echoing MIDI input to a second destination normally requires a second MIDI track with a copy of the same MIDI on it. In order not to have to record the same MIDI to two tracks (and sync any edits I might make), I use the free MIDIChFilter VST from CodeFN42 that echoes MIDI input to a virtual IN that can be assigned as input to multiple tracks. So basically I have three tracks:
Track 1 is a MIDI track that receives input from my keyboard and echoes it to MIDIChFilter.
Track 2 receives input from MIDIChFilter and echoes it to the main instrument (be it a hardware piano or a VSTi)
Track 3 also receives input from MIDIChFilter and echoes it to Pianoteq.
The way the resonance feature is implemented (not a true "sidechain" per Cakewalk CTO Noel Borthwick), Pianoteq 8 has to be instantiated as a plugin in the FX bin of an audio track in order for Sonar to "see" the resonance input. I use an "Instrument" track that combines MIDI and Audio functionality to host the plugin as well as echo MIDI too it. This routing is somewhat peculiar to way Sonar handles I/O to/from VSTis so I can't say how much if it is directly applicable to Logic, but hopefully that gives you some idea of what you need to do and is not just adding to the confusion (!).
I left out that the Audio/Instrument track of the "main" piano instrument is also sending audio to Pianoteq's "sidechain" input for resonance processing, but I think you already understand this part of the setup.
