Using Ultrabeat MIDI Controllers A-D
The MIDI Controller Assignments area at the upper edge of the Ultrabeat window enables
you to assign any MIDI controller shown in the menus to each of the four controller
slots: Ctrl A, B, C, or D.
These assignments enable external MIDI controller hardware—such as sliders, knobs,
aftertouch, or the modulation wheel of your MIDI keyboard—to control via modulation
sources in Ultrabeat.
To assign a controller
µ
Open the desired control menu (Ctrl A–D), and choose the controller name or number
that you want to use from the list.
To learn a controller assignment via MIDI
1 Open the desired control menu, and choose the -Learn- menu item.
2 Move the desired controller on your MIDI keyboard or controller.
Note: If no suitable MIDI message is received within 20 seconds, the selected control
reverts to the previous value/assignment.
Getting to Know the Ultrabeat LFOs
Two identical LFOs are available as modulation sources in the “mod” menu.
LFO is the abbreviation forlow frequency oscillator. The LFO signal is used as a modulation
source. In an analog synthesizer, the LFO frequency generally ranges between 0.1 and
20 Hz, which is outside the audible frequency spectrum. Therefore, this type of oscillator
is used only for modulation.
Note: The speed of the LFO in Ultrabeat can reach up to 100 Hz, which affords a number
of possibilities that analog synthesizers simply don’t offer.
