4.12 Modulation Envelope Amounts Section

In the Modulation Envelope Amounts section you can adjust how much the modulation envelope affects SPARK's
most important parameters.
The Modulation Envelope Amounts section allows you to significantly affect the way the sound
evolves over time and give it a more lively character. The modulation envelope determines
how the 8 parameters of SPARK are modulated by the Modulation Envelope section.
The – pW + K controls the amount of the modulation envelope signal that is added to
nob
the Pulse width of the Pulse oscillator. When the knob is in the vertical position, no envelope
modulation of the Pulse width takes place.
With the Fb o K you control how much the modulation envelope influences the feedback
Sc nob
to the FM inputs of the two oscillators.
The Fb F K is the most influential parameter of this section. It has great control over the
ilt nob
self-oscillation of the synthesizer. When Fb F is set to zero, self-oscillations would continue
ilt
independent from the playing of notes. If you want feedback oscillations only when a note is
played, you have to turn up the Fb F K . The modulation envelope then will damp the
ilt nob
feedback loop to its time-variant output. The Fb F K is a crossfader between a constant
ilt nob
1 and the modulation envelope signal as a multiplier for the feedback signal at the input of
the Ringmod/Filter section.
The amount of envelope modulation applied to the ring modulator is set with the rM K .
nob
The – c + K determines the amount of the modulation envelope signal that is added to
ut nob
the cutoff frequency in the Ringmod/Filter section.
The drive parameter of the Shaper unit is also important in feedback loops, since high input
gains before the saturator suppress the signal level and with it self-oscillations. For this pur-
