The Filter Section
The output signals of both oscillators, the ring modulator, and the noise generator are
passed on to Ultrabeat’s central Filter section (if they haven’t bypassed it through use of
the various filter bypass buttons). The Filter section offers a multimode filter and a
distortion unit.
The order that sounds are passed through the filter and distortion unit is determined
by the arrow found at the equator of the Filter section. Clicking the arrow switches
between the arrow up (distortion, then filter) and arrow down (filter, then distortion)
settings.
Note: A description of Ultrabeat’s filter parameters and a discussion on the basic
concepts of subtractive synthesis and analog filters follows. If you’re new to
synthesizers, please read “Synthesizer Basics on page 417 for more information.
The Multimode Filter
A click on the word “filter” in the upper middle section activates or deactivates the
multimode filter. In a deactivated state (the word filter is gray, and red when active), all
synthesis engine signals pass the filter unprocessed and are forwarded to the distortion
unit.
The multimode filter offers the following filter types: lowpass (LP), highpass (HP),
bandpass (BP), and band rejection (BR).
You can switch between the filter types by clicking the corresponding button directly
beneath the word filter.
