Ultrabeat

Ultrabeat overview
Ultrabeat is a synthesizer that is designed to create percussive sounds and polyphonic rhythms. It
also incorporates a powerful, integrated step sequencer, which you can use to create polyphonic
rhythmic sequences and patterns. See Ultrabeat step sequencer overview.
Most software synthesizers offer one synthesizer per plug-in instance. Ultrabeat, however, places
25 independent synthesizers at your disposal. These synthesizers—known as drum voices in
Ultrabeat—are optimized for the generation of drum and percussion sounds.
You can compare Ultrabeat with a drum machine that features 24 drum pads, plus a built-in
multioctave keyboard that can be used for polyphonic accompaniments, or bass or melody lines.
See Play and select Ultrabeat drum sounds.
The distribution of drum voices across the MIDI keyboard is as follows: a single drum voice
is assigned to each of the first 24 MIDI keys (spanning MIDI notes C1 to B2). The 25th drum
voice is assigned to the keys from the 25th MIDI key (C3) and above, enabling you to play this
sound chromatically.
25th drum voice can be
played chromatically.
