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