Hi
It sounds like you are using ASIO for BIAB and maybe Proteus VX at the same time.
I have found that BIAB is a bit 'flaky' when using ASIO so I tend to stick with MME audio drivers as only one 'program' can use ASIO at a time.
Other than trying these suggestions I'm afraid its a bit of 'try this try that' approach.
1.In BIAB use the MME audio drivers
2.In Proteus VX options/preferences/audio use the Direct Sound audio driver.
3.If that works good, if not try switching Proteus VX back to ASIO audio drivers.

The Midi Input driver in BIAB must be different to the output driver ...example input set to Yoke:2 and output to Yoke:1 would be fine.
Make sure the Use VST/DXi Synth option in BIAB is unticked.
