The voltage-controlled oscillator (VCO) is not the heart, but an
effect. The heart of the INM is the Imp , a voltage-controlled noise source.
The VCO is used to “color” the tone of the noise. While the actual signal
path is technically the same as traditional synths, with the Imp being used
to modulate the frequency of the VCO, the key to proper use of the INM
is that the Imp is the core, and the VCO is an effect. The control panel is
specically laid out to enforce this relationship (gure 2).
