Use Logic Pro Ultrabeat trigger mode
The way Ultrabeat reacts to a succession of incoming notes is set independently for each
sound. Parameters that control this aspect of Ultrabeat behavior are found in the trigger
mode section.
Trigger mode parameters
Trigger pop-up menu: Choose either Single or Multi trigger mode.
Single: A new trigger note cuts off the note that is currently playing.
Multi: When a new note is played, currently playing notes continue to decay in
accordance with their respective amplitude envelope settings (Env4).
Group pop-up menu: Choose between Off and 1 through 8. If two different sounds
are assigned to the same group, they cut each other off when a new note message is
received. Only one sound in the group can be played at a time.
A typical use of this feature is when programming hi-hat sounds:when playing a real
hi-hat, the closed hi-hat note cuts off or mutes the ringing of the open hi-hat. This
feature is often referred to as “hi-hat 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 in the group,
regardless of the note played.
Gate button: Turn the Gate function on or off. When active, the sound immediately cuts
off when the MIDI note is released, regardless of envelope settings.
Note: The Gate function ensures that a specific sound does not play—it can’t be
heard—after a note-off event sent from Logic Pro or the Ultrabeat internal sequencer.
Note length can be an important creative element when programming rhythm tracks.
Ultrabeat modulation
Logic Pro Ultrabeat modulation overview
Most sound parameters can be controlled dynamically (modulated) in Ultrabeat. Ultrabeat
provides two LFOs, four envelope generators, velocity, and four user-definable MIDI
controllers as modulation sources.
Ultrabeat modulation routings feature three key elements:
The modulation target: The synthesizer parameter that you want to modulate.
The modulation source: The parameter that modulates the target.
The via source: A secondary modulation source that can influence the intensity of the
first modulation source.
Note: You can use the same sources and the same via controllers in multiple modulation
routings.
