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 Fireface UCX II supports

ASIO Direct Monitoring

(ADM).


The Fireface UCX II MIDI I/Os 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
number of channels presented from the ASIO driver will change too. This may require a reset of
the I/O list in the audio software.
