10. Operation under ASIO
10.1 General
Start the ASIO software and select ASIO Fireface USB as the audio I/O device or the audio
driver.
Fireface UC supports ASIO Direct Monitoring (ADM).
The Fireface UC supports both MME MIDI and DirectMusic MIDI.
10.2 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 is reduced from 8 to 4.
At a sample rate of 176.4 and 192 kHz, the ADAT optical input and outputs operate 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.
