progressively slower and at 100% it never fades away. During recording, the SOS
is processed through a DJ-style filter whose response can be changed by holding the
SHIFT button and turning the LENGTH knob: at noon no filter is applied, going clockwise
an HPF is applied, going counter-clockwise an LPF is applied.
10.3 Oscillators
The module provides three stereo oscillators: one simple sine, one supersaw (inspired by
the Roland JP-8000), and a wavetable. While the sine oscillator can be used alone, the
other two are mutually exclusive and can be selected with the relative switch. Depending
on which one is selected, the DETUNE knob controls either the detuning of the 7 saws of
the supersaw or the selection of one of the 32 wavetables dynamically extracted from
the looper buffer.
The full pitch range of the oscillators is 8 octaves, from C0 to C7. The PITCH control
is centered on C and spans 6 semitones on either side. The current octave can be
selected by holding the SHIFT button and turning the PITCH knob.
The v/oct input is common for the three oscillators, is summed to the PITCH knob,
and tracks 10 octaves on the 0-volt to 10-volt range. The frequency is clipped if outside
the supported range.
Holding the SHIFT button and turning the DETUNE knob allows for altering the interval
betwen the oscillators: the frequency of one of the two sine’s channels and that of both
the supersaw and the wavetable oscillators are lowered one octave down at 0% and
raised one octave at 100% (default is 50%, unison).
11 Effect units
11.1 Filter
This unit is either a 2-pole multimode filter that can be switched between
low-pass, band-pass, and high-pass filtering, or a comb filter. The type can be selected
by holding the SHIFT button and turning the CUTOFF knob. When the unit is used as
a multimode filter, the CUTOFF knob controls the filter frequency cutoff (approximately
from 10Hz to 22kHz), while when used as a comb filter the knob controls the position of
the notches.
This filter has a unique feature - a chaotic noise generator that activates when the
RESONANCE knob goes past 75%. The output of the noise generator is then combined with
the input and filtered. Even when no input is provided, the noise is audible.
