cycle through the “all not filtered”, “all filtered” and
“combination filtered” states by adjusting the check
box from “check” to “X” to “box” and back.
You can use the + and - keys to scan up and down
through the 16 channels at any time in the Filter
window. This makes it easy to adjust the filter
setting for a particular type of message at one time
without having to shift focus from the channel
setting to the filter setting.
For example, suppose you wanted to filter the
MIDI Timing Clock messages being generated by a
drum machine connected to input 1. MIDI Timing
Clock messages are from a general class of MIDI
messages called “real time” messages. All real time
messages are from the even more general class of
“non-channelized” messages. So, first, you would
access the Filter window for the input 1 (see
“Changing a filter setting” on page 92). In the Non-
Channelized section, click the check box next to
Real time so a red “X” appears. This setting will
prevent MIDI Timing Clock messages from
passing through the port. The overall effect of this
setting will prevent Timing Clocks from being
routed to any outputs connected to input 1 or being
received by any MIDI software using input 1.
CHANNEL MAP WINDOW
The Channel Map window allows you to change
the MIDI channel of all messages passing through
an input or output port. You can “remap” the
channels in any way you wish. Remap only one
particular channel, any combination or all
channels. As with the filter settings, each port can
be configured to have independent channel
remapping settings. The MIDI Timepiece AV
defaults to no channel remapping (meaning
channel 1 maps to channel 1, channel 2 maps to
channel 2, etc.), and in most cases, this should be
the desired default.
Figure 10-15: The Channel Map window for the input named “K2500”
showing channel 1 being mapped to channel 3.
Making a channel map setting
To remap channels of MIDI messages for a
particular port:
1
Click on the port’s icon in the MIDI Routing
window.
2
With the port selected, click on the channel map
button above the selected port as shown in
Figure 10-7 on page 87.
3
Now, with the Channel Map window open,
select the channel you wish to remap on the left
side and enter the new (remapped) channel on the
right side.
You may make a remap setting for all 16 MIDI
channels.
You can use the + and - keys to scan up and down
through the 16 original channels at any time in the
Channel Map window. This makes it easy to enter a
number of remap channels at one time without
having to shift focus from the original channel
setting to the remap channel setting.
For example, you may want to use a keyboard that
transmits only on channel 1 to control a sound
module set to receive on some other channel, say 5.
Suppose the keyboard is connected to input 1 of
the MIDI Timepiece AV and the sound module is
connected to output 3. First, you would route input
1 to output 3 using the MIDI Routing window (see
“MIDI routing” on page 88). Next, you would
access the Channel Map window for input 1 in a
