message to be sent immediately following the
previous message in the list. This allows a group of
messages to be sent at once with a single up or
down movement of the pedal.
Figure 7-22: The pedal event sequence. Clicking the icon of an event
(inset) toggles its up/down status.
☛
Tip: you don’t have to always start the event
sequence with a “down” event. You can place an
“up” event as the first in the sequence, if you like.
For example, in the pedal event list shown above,
the following would occur when the pedal is used:
MAKING CLICK-TO-MIDI SETTINGS
The click settings are similar to the pedal settings
except that only a single MIDI message can be
triggered. Also, there is no notion of “up” or “down”
since a click-to-MIDI message is triggered by an
audio source as opposed to a pedal input. For
example, you could send the signal from a
microphone into the “PEDAL” jack of the MIDI
Express XT and mic a live snare drum. Using the
click-to-MIDI function of the MIDI Express XT,
the snare drum signal can be converted into a
MIDI note message used to trigger another
percussion sound in a drum machine or sampler.
This feature can be used for many other purposes,
too. Here are a few ideas:
■
Recording the click’s tempo map into a
sequencer
■
Slaving a sequencer to an audio click track
■
Triggering drum samples
To make a click-to-MIDI setting:
1
Route the Pedal icon in the MIDI Routing
window to the desired output(s) (as demonstrated
in Figure 7-21 on page 67.
2
Access the Pedal window by double-clicking on
the Pedal icon and set Input type to “Click”.
Figure 7-23: The click settings, including the decay and threshold
settings.
3
Set an appropriate decay and threshold in the
Input settings section.
Decay is meant to prevent doubled attacks. The
decay is the amount of time the MIDI Express XT
will wait before it begins scanning for another
click. Set the decay as high (long) as possible to
Pedal Action Result
Pedal down Program #57 gets called up on channel 1.
The volume gets set to 50 and then a note,
C3, begins to sustain.
Pedal up Note C 3 is silenced and program #3 is called
up, the volume is turned up and an E3 plays.
etc. etc.
