THE MIDI DATA PATH
As for MIDI data arriving and leaving your computer via
the MOTU USB MIDI interface driver, imagine it coming
and going from the MOTU interface as shown in
Figure 4-2. All channelizing and filtering is applied before
the input data arrives at the computer and after it is sent
from the computer. This is a great advantage as it frees up
your computer and MIDI software from having to deal
with the mundane (and time-consuming) chore of such
processing. Just configure your MOTU interface and let it
do all the work!
