Module: Shaper 1/2
Modulating model parameters
An envelope can modulate not only the amplitude
and frequency (pitch) of a signal but also other
parameters.
Neuron’s two resynators and the sound models
loaded into them offer infinite sound-shaping
without adding envelopes to the equation, so
imagine what mind-boggling possibilities envelopes
give you for modulating the model’s parameters.
Hard to envisage? Then call to mind the
aforementioned amplitude modulation and try to
picture what this kind of process could do to a model
parameter. Perhaps this will make the possibilities
more tangible: Take, for example, metallicity. The
note gains a metallic edge in the defined attack
time, dropping to sustain level during the decay
phase that defines how metallic the timbre will
remain for as long as you hold the key down. After
you release the key, the metallic sheen fades during
the release phase.
The parameter value defined in the resynator
determines the limits of the envelope’s influence on
the model parameter. The minimum value is the
currently selected parameter value, the peak value is
the maximum possible parameter value (127). In our
example, this means that at a metallicity value of 70
the envelope modulates the parameter within the
value range of 70 and 127.
So how is this modulation configured in Neuron? The
envelope defined in shaper 1 (shaper status =
par.level)modulates the resynator 1’s model
parameters, shaper 2 influences resynator 2’s
parameters. As a prerequisite for the modulation, the
given resynator’s contour contr. button must be set
to shaper. The envelope’s depth can be determined
separately for every parameter level.
Velocity-driven envelope effects
Have you ever wished that you could define an
envelope just once and have it modulate at different
intensities in accordance with how hard you strike
the keys? Wish no more: Neuron makes it happen:
The envelope’s depth parameter is modulated via
your key pressure when you enter a value other than
zero for the velo depth parameter (see the parameter
description on page 109).
