choice motivated by the compatibility windows / mac / linux, and the versatibilité.
used especially in setting DM24 backup (dump noon), or to have a midi ports on any PC.

UTILIZATION

walk impec Linux, not tested with other OS.
Software used: amidi (enregisrement sysex), or aplaymidi command line: D

OVERALL OPINION

I love versatibilité, (each port can be input or output) and the simplicity of the product (all electroniqe is in the usb plug).
I do not like the smell of plastic, which takes the nostrils ...
for me it's the Swiss Army knife noon ...
