9. Operation under ASIO
9.1 General
Start the ASIO software and select ASIO MADIface USB as the audio I/O device or the ASIO
audio driver.
The Digiface AES supports
ASIO Direct Monitoring (ADM).
The Digiface AES MIDI I/O can be used with both MME MIDI and DirectMusic MIDI.
9.2 Channel Count under ASIO
At a sample rate of 88.2 or 96 kHz, the ADAT optical input and outputs operate in S/MUX mode,
so the number of available channels per port is reduced from 8 to 4. At a sample rate of 176.4
and 192 kHz, the ADAT optical input and output operates in S/MUX4 mode, so the number of
available channels is limited to 2.
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.
