Since I use software synths and MIDI controllers with ASIO4ALL and BiaB on my laptop when travelling and very rarely have any issues with that, I'm thinking that the odd man out in your setup is the Pianoteq software.

So that is what I'd be investigating if I were you, maybe there are internal Settings inside the Pianoteq that need to be tweaked, or something like that.

To be positive that is the case, I'd temporarily invoke *other* MIDI software synths and test the latency with BB and those other synths with the setup, for if all the other software synths can be made to work without the latency issue, then the Pianoteq software would definitely be the place to investigate this.
