modulation with the difference that the harmonics of the incoming signals are not left intact.
This often causes inharmonic spectra. The signal from the ring modulator is then fed to the
filter, and subsequently to the shaper.
The voice delay in the Special section is a key element in the creating the feedback signal, it
determines which frequencies are excited in the feedback loop. The frequency shifter is the
last structure that allows direct manipulation of the frequency content of the spectra.
In the Mixer section, the signals from different points along the described path can be tapped
and mixed together to be processed by the Effects section. The effects are always running
and the degree that the output of the Mixer section is processed by a certain effect unit is
controlled by the unit´s M K .

The feedback signal is put together in the S using the "FB Mono" and "Int –

Ext" crossfaders, where turning the knobs to the right increasingly crossfades to the signal
that is represented on the right side of the crossfader in the figure. By now it is fairly obvious
that the sound that reaches the instrument output at the end of the effects chain can have a
wide range of timbres and evolving behaviours made possible by manipulating the feedback
loop. Even with good knowledge of the signal flow the effects of changing the parameters can
often be quite surprising, but that is also part of the fun when exploring SPARK's capabilities.
