7.4.8.5. Gater
•
The next press of the Effect-Menu button will bring
you the next message:
Track >_2_____m<
Gater:OFF
−
To the exception of the Note-Event where a Note-Off
will be sent after its related Note-On, all other Event
Type will send only their own event data.
−
If the Gater is activated, with an Event Type other than
a Note-Event, at the place where a Note-Off would
appear, the same Event Type as the one selected will be
sent with a fixed value of zero.
•
Setting the Event Type to Controller and the Note
Number (in fact the controller number) to 7, which is
the standard MIDI volume controller, sustained notes
played on the same MIDI channel will be minced.
•
These notes can be generated by the Schaltwerk itself
or come from any other source, in which case a merger
is required, as the Schaltwerk will not retransmit the
MIDI events present at its input.
•
In this example, the Gater works as a MIDI-triggered
Noise-Gate. Producing sustained chords, rhythmically
chopped, without retriggering the keys, are not a
problem anymore.
•
Other applications can be done very easily by selecting
a different Controller number or a different Event
Type.
7.4.8.6. Chord Trigger
The next press of the button will bring:
Track >_2_____m<
Chord-Trig:OFF
•
This effect is also dependent on external MIDI Note-
Events and requires to have a MIDI input specified.
•
The Chord-Trigger beats the sustained notes
automatically according to the track rhythm.
•
The note values are transposed with the values taken
from the respective steps and their velocities are
multiplied by the step’s ones accordingly.
•
At first sight, you can easily differentiate the Chord-
Trigger functions from the note transposition and
velocity multiplication functions also found in the
Gater. In contrast, no controller value, nor controller
value zero are offered, but for each step a whole
packet of Note-Events can be sent. This function is
restricted to Note-Events, while the Gater function
can rhythmically control almost any type of MIDI
event.
•
Contrary to the Gater, the sound is retriggered with
the Chord Trigger and does not hold. Furthermore, a
MIDI merger is not necessary as the Note-Events are
directly produced by the Schaltwerk.
✌ You can experience timing inaccuracies and a
shaking feel if a huge quantity of Note-Events
must be produced in a single step. In the Gater
there is a limit of 2 events per step per track,
while the theoretical limit for the Chord Trigger is
of 2 × 128 Note-Events per step.
•
A hold function is available through the sending of the
Chord-Hold-Controller (see page 26). While an ON-
message is received and active, so will all received
Note-On messages (and their corresponding Note-Off
messages) until nothing else is registered, or an OFF-
message arrives.
•
The “ON” message is indicated in the menu by a “!”
sign at the end of the row.
