Ultrabeat modulation<br />
Ultrabeat modulation overview<br />
Most sound parameters can be controlled dynamically (modulated) in Ultrabeat. Ultrabeat<br />
provides two LFOs, four envelope generators, velocity, and four user-definable MIDI controllers as<br />
modulation sources.<br />
Ultrabeat’s modulation routings feature three key elements:<br />
••<br />
The modulation target: The synthesizer parameter that you want to modulate.<br />
••<br />
The modulation source: The parameter that modulates the target.<br />
••<br />
The via source: A secondary modulation source that can influence the intensity of the first<br />
modulation source.<br />
Note: You can use the same sources and the same via controllers in multiple<br />
modulation routings.<br />
Mod and via modulations in Ultrabeat<br />
You can modulate a sound parameter using an adjustable value—the modulation depth<br />
or intensity—with the mod parameter. You can choose between two LFOs, four envelope<br />
generators, and Max as sources for this modulation.<br />
Via influences the modulation effect as follows. The depth of the first modulation (mod) can be<br />
modulated by a separate, independent source. The intensity of this secondary modulation is set<br />
with the via parameter. The sources for via modulations include velocity and four user-definable<br />
MIDI controllers.<br />
A typical via modulation usage would be to increase a pitch sweep as you play at higher<br />
velocities. The harder a key is played, the higher in pitch it sounds—which is ideal for synthesized<br />
tom-tom sounds, for example. To create this routing, you would use an envelope (Env) as the<br />
mod source for oscillator pitch, and Velocity (Vel) as the via source.<br />
Consider the following example:<br />
The default Cut (Cutoff) parameter value is 0.50. No modulation source has been chosen in either<br />
the (blue) mod or (green) via pop-up menu. Both are Off in the image below.<br />
When a modulation source is chosen from the mod pop-up menu (Env 1 in the image below),<br />
the ring around the knob is turned on. Drag in the ring to set a value (0.70 in the example) for<br />
the Cut parameter—when affected by the mod source.<br />
