The bank switching is a known problem with other MOTU USB devices, and has
been "solved" by using specific firmware releases (e.g. for the MOTU
Ultralite AVB) which may not be available anymore or for your specific
device.
I do not believe that the aliasing is caused by bank switching, but by
(possibly) an ALSA driver bug. It generally goes away within a few minutes
or on device restart.
Hi list,
can report that the Motu M64 Madi interface does work with a limited
channel count of 24 for input and another 24 for output (instead of 64
each). So if you are coming across a venue or employer that already has
one, you are good to go. Sample rate needs to be set on the device
before starting jack. Of course, buying the card for oneself for so much
money getting only one third of the channels seems useless linux users
IMHO.
I can add now that the card does not work reliably in class compliant
mode with external sync clocks. It will randomly switch back and forth
output channels in banks of eight, cause clicks and distortion and
aliasing artifacts.
