I'm using reaper as my DAW and I use Superior Drummer under ASIO4ALLv2. Once the drums are taking care of, I need to switch the driver to the M-AudioUSBAsio so that I can record my guitars. The issue is I can only hear the drums at a very low volume when I record the guitars (because of the m-audio driver). So do I have keep switching back and forth between drivers in order to record with the drums? I've been recording under the M-audio driver, then switching to the ASIO4ALL to hear it with the drums. Thank you - Jon
