Depending on the status of each signal flow button, the output signals of both oscillators, the ring modulator, and the noise generator are routed to the Output section of Ultrabeat. This routing is either direct or through the Filter and Distortion section.
The Output section passes signals through both equalizers (EQ), then on to the Pan Modulation/Stereo Spread section (in a preconfigured order) before the final level is set for the selected sound and the trigger behavior is adjusted.
Both equalizer bands have almost identical features. Their parameters are explained jointly, but you can, of course, adjust band 1 (the lower EQ in the Output section) and band 2 separately.
Band 1 offers a low shelving EQ whereas band 2 features a high shelving EQ.
In shelving mode, activated by clicking the upper EQ type button, all frequencies above or below the set frequency are either increased or reduced.
In peak mode, activated by clicking the lower button, only frequencies located near the set frequency are affected.
Note: Shelving EQs behave much like synthesizer lowpass and highpass filters. The key difference is that lowpass and highpass filters merely dampen certain frequencies (filter them out), whereas shelving EQs also allow these frequencies to be boosted.
Option-click a Gain knob to set it to a neutral position. Alternatively, you can click the tiny 0 above the Gain knob.
Option-click the Hz parameter to set the value to a neutral position. This is 200 Hz for the first band and 2000 Hz for the second. The selection of these default frequencies was made in accordance with the different shelving characteristics of each frequency band. Band 1 is designed to filter low frequencies and band 2 is designed to filter high frequencies.
With shelving filters, as the Q value goes up, the area around the threshold frequency becomes more pronounced.
With the peak EQ, Q determines the width of the frequency band selection: low Q values select a broad band whereas high Q values select a very narrow band to be boosted or reduced with the Gain control.
Each EQ band displays parameter changes on a frequency response curve. The display provides immediate access to the Gain, Hz, and Q parameters of each band.
Horizontally drag to change the EQ frequency.
Vertically drag to change the Gain.
Drag the handle shown at the peak (maximum point) of the EQ curve to change the Q factor.
The EQ’s output signal is passed along to the Pan Modulation/Stereo Spread section where the placement of the sound in the stereo field can be modulated (Pan Modulation mode), or the stereo basis of the sound can be broadened (Stereo Spread mode).
Pan Modulation varies the panorama position of a drum sound with a “mod” (and “via”) source.
Note: The modulation set here is relative to the panorama position set in Ultrabeat’s Mixer in the Assignment section.
Note: You cannot directly move the red line that represents pan position shown in this section. In order to move the line, rotate the pan knob in the Mixer section.
Stereo Spread broadens the stereo image, making it wider and more spacious.
The Voice Volume knob adjusts the output volume of individual drum sounds. To be more exact, you are setting the maximum level for the selected drum sound with Env 4, following the attack phase of Env 4.
Note: Envelope 4 (Env 4) is hard-wired to voice volume—the level control for the selected sound. Each sound in the kit also has a further three envelopes and other modulation sources available for control of other synthesis parameters.
The intensity of Envelope 4’s impact on Voice Volume can also be modulated with a via source.
Note: Voice Volume precedes the sliders in the mixer. This approach allows the starting volume of individual drum sounds to be set independently of their relative levels in the drum kit mix, which you adjust in the Assignment section mixer.
The way Ultrabeat reacts to a succession of incoming notes is independently defined for each sound. Parameters that provide control over this aspect of Ultrabeat’s behavior are found in the Trigger Mode section, below the Voice Volume knob.
A typical use of this feature is when you’re programming hi-hat sounds: when playing a real hi-hat, the closed hi-hat note cuts off or mutes the ringing of the open hi-hat. This feature is often referred to as hi-hat mode.
Note: While in Single Trigger mode, only the currently sounding note of the same sound is cut off. A sound that is assigned to a group cuts off all other sounds, regardless of note, in the group.
Note: The Gate function ensures that a specific sound does not play—it can’t be heard—after a note-off event in a host sequencer such as Logic Pro, or Ultrabeat’s internal sequencer. Note length can be an important creative element when you are programming rhythm tracks.
