NOTES
• Data received via the MIDI IN-A terminal is transmitted directly to the computer
(via the TO HOST terminal) without affecting the Parts of the MU128. To have
Parts on the MU128 respond to data received via the MIDI IN-A terminal (for
example, to hear sounds while entering data to the computer), make sure that the
MIDI Thru (or MIDI Echo) function on the music software is set to on. This func-
tion allows you to route data coming into the computer back out again.
• Providing your particular music software is capable of multi-port operation, you
can independently play all 64 Parts of the MU128 from your computer. With a
second multi-timbral tone generator, you can even expand this to a full 80 Parts.
To do this, connect the tone generator to the MIDI OUT terminal, then set the
Thru Port parameter (page 160) to a value of 5 or higher — giving you an addi-
tional 16 MIDI channels.
