CONTROLS AND USAGE
Here is a brief explanation of the controls and their usage, described
in the same order as the signal path (see figure 1).
IMP
Domain, Frequency, Range and Width: • Technically, all four
describe the same Function: what frequency the Imp puts out. The total
possible range of the Imp, however, is from subsonic to ultrasonic, and
accessed in different ways requiring multiple controls for fine-tuning.
Domain: • The first stage of frequency selection. Domain selects
one of four wide bands of the overall range. Four Domain is lowest, One
is highest (in frequency). Four is audio, One is nearly ultrasonic. The One
Domain is where you will find the oddest/most ethereal Noises: static, wind,
the impression of voices. It has a lot of what seem to be dead spots, but it is
worth the time to wander the Domain and see what can be found.
When modulating the VCO, the greater effect is when the VCO
and the Noise frequencies are closer together, i.e., the effect is
minimal when the VCO is in the bass range and the Noise Domain
is in One, but extremely dominant when similar in frequency.
Frequency: • This is the main frequency control within the selected
Domain - it sweeps over the entire Domain (depending on Range, see
following). The Fine control sweeps up to 1/5 of the size of the band that
Coarse does.
Range: • This controls how wide of a sweep Frequency covers.
Fine control same as with Frequency.
Width: • This one is a bit more esoteric: it controls the “width” of
the band of the current domain that the Fine controls cover, hence the “up
to 1/5”. In Domain 1, wide open is best. In Domain 1 the bands of sound
are very narrow, so it is best to set the width all the way down to find the
hidden sweet spots.
In other words, a quarter of the possible frequency range is selected
by Domain, and the other controls select how much of that Domain the
frequency control can sweep across. The Coarse joystick is for a broad
sweep over the Domain, and the Fine joystick is for finding the perfect
“sweet spot”.
