Don't know if this is a problem- the Presonic is 24 bit- can RealBand or PTPA HANDLE 24 bit? Answering my own question, I chose 24 bit, 44.1 from the Audio settings window. It scrolls thru the recorded audio, then stops and brings up the "RealBand has encountered a problem and needs to close". When I reopen it, I have to go through and chose everything all over again! The ASIO driver, inputs/outputs- very frustrating.
