Using the Ultrabeat Noise Generator
The Ultrabeat noise generator offers extensive features, enabling the creation of a wide
range of percussive sounds and sound elements. The noise generator also has its own
filter—which functions independently of the main Ultrabeat Filter, although this can also
be used on the overall sound.
Technically, a noise signal contains all tonal frequencies, at a more or less equal volume
level. As all frequencies in the spectrum are audible, it makes it difficult for human beings
to isolate, and therefore discern, any tonality (pitch) in a noise signal. Despite this, or as
a direct result of it, noise is an indispensable ingredient when creating drum sounds.

On/Off button: Activates or deactivates the noise generator.
Note: When programming a drum sound, you can turn the individual sound sources
on or off with the On/Off buttons. You can also listen to the individual components of
the sound separately this way, and remove them if desired.
Filter Type buttons: Switch the noise generators integrated filter between lowpass,
highpass, and bandpass filter types.
LP (lowpass): This filter type allows frequencies that fall below the cutoff frequency
to pass. When set to LP, the filter operates as a lowpass filter. The filter slope is fixed
at 12 dB/octave in LP mode.
HP (highpass): This filter type allows frequencies above the cutoff frequency to pass.
When set to HP, the filter operates as a highpass filter. The filter slope is fixed at
12 dB/octave in HP mode.
