9. Operation under ASIO

9.1 General

Start the ASIO software and select RME Thunderbolt ASIO or ASIO MADIface USB as the

audio I/O device or the ASIO audio driver.

The Fireface UFX+ supports ASIO Direct Monitoring (ADM).

The Fireface UFX+ 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.

The same is true for MADI, the number of channels is reduced to 32 (Double Speed) and 16

(Quad Speed).

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.
