Ultrabeat’s 24-drum pad assignment is compatible with the widely adopted GM (General MIDI)
MIDI Drum note mapping standard. If your MIDI keyboard is limited to two octaves or does not
support transposition, use the Transpose parameter of your host application to shift incoming
MIDI notes up or down one or more octaves.
Note: For clarity, and to maintain the drum machine analogy, this guide refers to the
independent synthesizers as drum sounds. A combination of drum sounds forms a drum kit.
Ultrabeat interface
Ultrabeat’s user interface is divided into three main sections.
Assignment section
Synthesizer section
Step sequencer
••
Assignment section: Displays all drum sounds in a drum kit. You can select, name, and organize
drum sounds here. This section also includes a small mixer, used to adjust the level and pan
position of each sound. See Ultrabeat Assignment section overview on page 330.
••
Synthesizer section: Used to create and shape individual drum sounds. The parameters of the
drum sound selected in the Assignment section are displayed in the Synthesizer section. See
Ultrabeat Synthesizer section overview on page 338.
••
Step sequencer: Used to create and control sequences and patterns. A sequence triggers a
single drum sound, and can consist of up to 32 steps. A pattern contains the sequences for
all 25 sounds. You can trigger and control sounds with the step sequencer in place of—or
in addition to—MIDI notes entering Ultrabeat from your host application or keyboard. See
Ultrabeat step sequencer overview on page 370.
