9. Operation under ASIO
9.1 General
Start the ASIO software and select ASIO MADIface USB as the audio I/O device or the audio
driver.
The MADIface USB supports ASIO Direct Monitoring (ADM). Both MME MIDI and DirectMusic
MIDI can be used.
Note: If an AES signal is applied to the BNC input, and Coaxial is selected as Input, the AES
audio signal will appear on channels 1/2 in TotalMix FX and the recording software. Channels 3
to 64 then carry no audio data.

9.2 Channel Count under ASIO

The MADIface allows the use of sample rates up to 192 kHz via the MADI interface. For this to
work single-channel data is spread to two or four channels using the Sample Multiplexing tech-
nique. Therefore the number of channels is reduced to 32 or 16 respectively.
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 and a reassignment of the channels within the project.
