MOTU Micro Lite [74/166] Channel map

CLOCKWORKS FOR MAC OS 9

CHANNEL MAP

The Channel Map window controls the channelizing of

MIDI data on all MIDI IN and MIDI OUT cables. With

complete ﬂexibility, this window can switch data from its

current MIDI channel to any other channel immediately

when the data either enters or exits your MOTU interface.

Figure 6-24: Use the pop-up menus to choose the MIDI device input or output

you would like to remap. Then change the MIDI channel numbers as desired.

Click the Default button to restore all mappings to their default state (channel

1 to channel 1, 2 to 2, etc.)

Channel mapping basics

A simple way to think of channel mapping is this: imagine

that each MIDI IN or MIDI OUT port connected to your

MOTU interface has a ﬁlter just inside the socket. MIDI

data enters the ﬁlter on one channel and as it passes

through the ﬁlter, it gets switched to a different channel.

On a MIDI IN port, data enters on a given channel. But

before it goes anywhere else, either to the Macintosh or to

a MIDI OUT cable, the Channel Map window can switch

the data to a different MIDI channel.

On a MIDI OUT cable, data exits the interface. But before

it does, the Channel Map window can switch the data to a

different channel.

Using channel mapping

Channel Mapping like this is useful in many different

situations. For example, you may have a MIDI keyboard

that only transmits data on MIDI channel 1. If you want to

transmit its data on a different channel, you can map

channel 1 on the keyboard’s MIDI IN cable to any other
