You can use a piz midikeyboard.dll
https://code.google.com/archive/p/pizmidi/downloads
get the latest pizjuce 64 and/or 32
load MiniHost into the piano track and load midikeyboard.dll into that and load a virtual instrument also that you send the midi out to.
The green is midi in/out and yellow audio in/out.
Drag a connection between them, right click to remove, drag up/down for level.
