(note that at sample rates above 96Khz only the first two outputs are
enabled).
----WINDOWS REQUIREMENTS----
Building the mixer on Windows requires the tusbaudio SDK from Thesycon. The
default location for the SDK is C:\Program Files\XMOS\tusbaudiosdk\
If it can be found on a different path then this can be changed in
Makefile.Win.
The mixer app on windows makes use of a USB dynamic library, also from Thesycon.
If required please contact thesycon.de for support.

The channel map units are extension unit with init ids 51 and 52. This unit
lets you implement arbitrary routings including loopbacks.

The mixer is controlled on macOS via the command line utility
