MIDI channel. To the rest of the network, it will then

appear as if the keyboard is transmitting on the new,

destination channel.

Muting and remapping

For information about when muting occurs before

channel mapping and vice versa, see “Muting and

remapping” on page 77.

MUTING

The Event Muting window is a sophisticated MIDI data

ﬁlter that controls what types of data will be sent and

received by each MIDI OUT and MIDI IN cable. You can

ﬁlter out any type of MIDI data on any channel on any

cable. In addition, each MIDI channel can have its own

unique muting setup. The Event Muting window shows

the muting status for each type of data on all MIDI

channels and all cables at once, giving you immediate

feedback on the state of your interface.

Muting basics

A simple way to think of data muting is this: imagine that

each MIDI IN or MIDI OUT cable on your MOTU

interface has a ﬁlter just inside the socket. A MIDI data

stream enters the ﬁlter and then continues on past the ﬁlter

with certain types of data removed. The ﬁlter has simply

“swallowed” the data types that are being muted.

On a MIDI IN cable, data is muted before it enters the

interface. On a MIDI OUT cable, data gets muted just

before it gets transmitted out of the interface.

☛ When data is muted on a MIDI IN port, the light on

the front panel still blinks when the data is received on the

port. Don’t be concerned. The light blinks to let you know

that the interface is indeed receiving the data on that port.

However, the data does get muted. (On output, however,

since muted data doesn’t actually get sent, the light does

not blink.)

Whenever you would like to mute data, begin with the

following procedure:

1 If you have more than one MOTU interface, select the

box you want to mute in the Device List window in

ClockWorks. See “The Device List window” on page 55
