Okay, here it is in plain laymen's English:


When "Use DXi" is checked and the "Route MIDI Thru to..." is also checked, the Thru track of BiaB, which is the track your keyboard connects to, is set to bypass the DXi synth and instead send the MIDI Output from the Thru track and channel directly to whatever you have highlighted as MIDI choice in the upper MIDI Output window, which is not for DXi choices.

This is very handy, especially if your keyboard has built in sounds, you can highlight the physical MIDI output in the upper window and when theh Use DXi is checked whatever you play on the keyboard gets routed to the keyboard's internal hardware synth. Or, you might have one of the older non-DXi software synths highlighted there, in which case the keyboard is routed to there instead of the DXi synth.

I have found that use of ASIO sound drivers (or the ASIO4ALL converter for built in soundcards) plus DXi synth with the "Route to Thru" UNchecked works fine here for playing in realtime. I like the sounds of the VSC DXi and the only trouble I have is occasionally when I first start up BiaB I can't hear the keyboard when I play it until I first hit Play and then Stop. After that, I can play the keyboard whether or not BiaB is playing.

It works.

Just usually takes a bit of shakedown time and learning and setting those controls and drivers to the right settings.
