Sometimes I have to hit the Play button before I can hear notes I play on the Thru channel when using Software DXi/
VSTi MIDI synths.

In other words, just changing to one and then expecting to be able to hear it immediately doesn't work. I think it is a matter of the software somehow getting set or "focus".

Anyway, after hitting the Play button, and while that song is playing for a few bars, I then hit the keyboard and can make sure I hear the chosen synth playing, then I can hit the Stop button.

And after doing the above, I can play the keyboard and hear it via the synth for the rest of that particular bb session whether or not the song is playing.

Give that a try.
