394 Chapter 24 Ultrabeat
Using MIDI to Control the Sequencer
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, playback, and Voice Mute mode.
Pattern Mode
If activated, you can switch and start patterns via incoming MIDI note commands.
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. 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).
 Sustain: The reception of a MIDI note starts the pattern and it continues playing in
an infinite loop until the corresponding MIDI note is released.
 Toggle: The reception of a MIDI note starts the pattern and it continues playing in an
infinite loop until the next note is received. If it is the same note, the pattern stops
immediately. If it is a different note, the sequencer immediately switches to the new
pattern.
Note: In Toggle mode, you can confidently switch between patterns in the middle of a
bar—the sequencer will stay in time and will automatically jump to the corresponding
beat of the new pattern. This isn’t the case in One Shot Trigger mode, however, because
the moment you switch in this mode, the new pattern is started from the beginning.
 Toggle on Step 1: The behavior is as per Toggle mode except that the pattern change
or stop occurs the next time beat 1 is reached—at the beginning of the next pattern
cycle.
