I have been running SONAR in ASIO mode and B&B in MME mode together to do drag and drop (D&D) and this works fine. Today I switched B&B from MME to ASIO (No real good reason to do this for D&D but done merely as an experiment).

If B&B is loaded first, the program works OK but then loading SONAR (with ASIO) at the same time, SONAR says it can’t find the UA-4FX audio interface. If I run SONAR (with ASIO) first things are OK but then trying to run B&B with ASIO at the same time I get an invalid pointer error in B&B and access violation as follows:

“Exception EInvalid Pointers in module bbw.exe at 00004FB9”

and then

“Access violation at address 100025B9 in module Rdaw1061.dll”

Switching B&B back to MME and running simultaneously things are sweet.

Note that running both in MME mode at the same time also works (I was using this before switching SONAR to ASIO to delete the guitar input latency.)
