“Which ASIO driver should I use with Edirol’s UA-20 and Digital Performer?”
We’ve found that the ASIO2 drivers (16 or 24 bit) for the UA-20 work great with Digital Performer 3. You may find that Digital Performer’s “Configure Hardware Driver” window alerts you that there is no compatible device attached, but if you continue choosing the UA20 ASIO2 driver, it will work. Additionally, make sure that the UA-20’s ADVANCE mode switch is ON when using ASIO drivers. With this information you should be set!
