9.1 General
Start the ASIO software and select ASIO MADIface USB as the audio I/O device or the audio
driver.
The Digiface Ravenna supports
ASIO Direct Monitoring (ADM).
9.2 Channel Count under ASIO
In Single Speed Speed (44.1 and 48 kHz) 128 input and output channels each are available.
Double Speed (88.2 and 96kHz) reduces the number of available channels to 64 each. Quad
Speed (176.4 and 192kHz) reduces the number of available channels to 32 each.
Note: When changing the sample rate range between Single, Double and Quad Speed the num-
ber of channels presented from the ASIO driver will change too. This may require a reset of the
I/O list in the audio software.
