Trigger and Group Menus
The manner in which Ultrabeat reacts to a succession of incoming notes is individually
defined for each sound. These parameters are found in the output section, below the
Voice Volume knob.
Clicking the button below the Trigger label opens the Trigger menu, allowing you to
choose between Single and Multi trigger modes.
• Single: A new trigger note cuts off the (same) note that is currently playing.
• Multi: When a new note is played, preceding (currently playing) notes continue to
decay in accordance with their respective amplitude envelope settings (Env 4).
Clicking the button below the Group label opens the Group menu, allowing a choice
between the Off and group 1 to 8 settings. If two different sounds are assigned to the
same group, they will cut each other off. A typical use of this facility is when you’re
programming hi-hat sounds: when playing a real hi-hat, the closed hi-hat note cuts off
and mutes the ringing of the open hi-hat. This function is often referred to as “hi-hat
group” mode.
Note: While in Single Trigger mode, only the currently sounding note of the same
sound is cut off. A sound that is assigned to a group cuts off all other sounds
(regardless of note) in the group.
Clicking on the Gate button turns the Gate function on and off. If active, the sound is
immediately cut off as soon as the MIDI note is released (MIDI note off), regardless of
envelope settings.
Note: The Gate function ensures that a specific sound does not play beyond a note off
event, as defined in the sequencer. A corresponding rhythmic definition of the exact
note off time is achieved with the Gate Length parameter in Ultrabeat’s step sequencer.
Logic’s sequencer allows you to quantize note off events, or precisely edit them
manually. Note length can be an important creative element when programming
rhythm tracks.
