Frequency: This knob has two parts, one for coarse tuning and the other for fine-tuning. The outside ring sets
the octave of the oscillator frequency: you can set it from -2 to +2 octaves, or it can be set to Low. This “Low”
setting gives a very low frequency oscillator, which can be used for effects. The inside part of the knob fine-
tunes the frequency. When tuning with the left mouse button, it sets the frequency by semitone steps. When
tuning with the right mouse button, it fine-tunes the frequency with more precision.
Level: This knob modifies the output level of each waveform. This can be useful for blending the mix of
the waveforms, and setting the amount of modulation created between them.
The oscillator’s frequency, shape and level can be modulated with control or audio signals, thanks to the
matrix connection (for shape, see the advanced matrix setting panel).
12.1.2 Filter:
There are three modes for this low pass filter which
can be selected by the horizontal switch:
• 12-db/Oct-attenuation mode.
• 18 db/Oct self-oscillating analog filter.
• 24 db/Oct self-oscillating analog filter.
Frequency: Sets the cut-off frequency. It can be modulated (audio or control rate) by connecting a pin at
the corresponding destination in the matrix.
Response: Sets the emphasis (the Q-factor) of the filter. If set at over 3.8, it begins to self-oscillate for
the 18 and 24 db modes. The response can also be modulated (see advanced matrix explanation).
Level: Sets the output level of the filter.
Note: The internal non-linearities of the 18db and the 24-db filters are not the same. The 18-db filter has
been finely emulated reproducing as closely as possible, the behavior of the original 18db diode layer filter.
12.1.3 Envelope Shaper:
The envelope shaper of the synthesis part is linked
with an internal amplifier (it is the only internal
connection of the synthesizer)
The amount of the amplifier level modulated by this
envelope is set by the TRAPEZOID knob, and the
output level is set by the SIGNAL knob.
The envelopes of the XILS 4 have two modes. The Trapezoid is as per the original model, whereas ADSR is
like that found on almost all standard synthesizers.
