This is how it works in Sonar with an USB sound card so I’ll assume that this will work with Reaper:
1-set BiaB to MME drivers
2-shut down BiaB then restart BiaB – make sure it is still in MME mode
3-load song, set BiaB to plug in mode
4-load Reaper using ASIO drivers

this should work – I hope it helps.


PS-an after thought if the above doesn't work. Set both BiaB and Reaper to MME. Repeat steps 3 + 4. Save song in Reaper then set Reaper to ASIO and continue.


I phoned my wife and asked her if she wanted me to pickup fish and chips on the way home.
She just grunted.
She still regrets me naming the twins.
