BiaB MIDI guitars NEVER sound ok to me, especially strummed acoustics.<...>
That depends on your synthesizer. MIDI has no sound, but triggers sounds in your synth. Some synths have better guitar sounds than others.
It also depends on the musician. Is the chord in a guitar-like inversion. Since BiaB choose the inversion to play, that can be fixed after exporting. Are the notes all played at the same time or in a strum pattern?
Also, there is something called "Home instrument bias". To a guitar player, the guitar sounds might never sound right, but for a casual listener or a horn player, those guitar parts might be just fine.
