9. Operation under ASIO

9.1 General

Start the ASIO software and select ASIO Fireface as the audio I/O device.

The Fireface 800 supports ASIO Direct Monitoring (ADM).

The Fireface 800 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.

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.
