• Alter Gate (Time): Randomly changes the note lengths of all steps while retaining the
selected beats (the trigger row remains unchanged).
• Randomize Vel(ocities): Same as Alter Velocities, but random parameter alteration is
more pronounced.
• Randomize Gate (Time): Same as Alter Gate, but random parameter alteration is more
pronounced.
Using MIDI to Control the Sequencer
As mentioned earlier, pattern performance can be influenced by incoming MIDI notes.
This allows you to spontaneously interact with the step sequencer, making Ultrabeat an
excellent live performance instrument. The manner in which Ultrabeat reacts to MIDI
control is determined by the Pattern and Mute Mode buttons and the Playback menu.
Pattern Mode
The On setting allows patterns to be switched or started via incoming MIDI note on/off
commands.
In this mode, the Transport button turns blue to indicate that it is ready to receive
incoming control commands.
MIDI notes C-1 to B0 switch between patterns: C-1 selects pattern 1, C#-1 pattern 2
and so on up to pattern 24, selected when MIDI note B0 is received.
Playback Mode
Pattern reactions to incoming MIDI notes is set in the Playback Mode menu.
The menu is opened by clicking on the field to the right of the Pattern Mode label on
the bottom-right edge of the Plug-in window. You will find the following options here:
• One Shot Trigger—The reception of a MIDI note starts the pattern, which plays once
through its cycle, then stops. If the next note is received before the pattern has
reached its final step, the new note stops playback of the first pattern and the next
pattern begins playing immediately (this can be a different pattern or the same
pattern, depending on the MIDI note received).
