These footage values allow you to switch the pitch in octaves. 32 feet is the lowest, and
2 feet, the highest setting. The origin of the term feet to measure octaves, comes from
the measurements of organ pipe lengths.
Wave
Wave allows you to select the waveform of the oscillator, which is responsible for the
basic tone color. You can freely set any pulse width in-between the square wave and
pulse wave symbols. The pulse width can also be modulated in the modulation section
(see the “Router” section, on page 192). Modulating the pulse width with a slowly
cycling LFO, for example, allows periodically mutating, fat bass sounds.
Sub
The sub oscillator delivers square waves (one and two octaves below the frequency of
the main oscillator), as well as a pulse wave (two octaves below the frequency of the
main oscillator). In addition to pure square waves, the waveform switch allows
selections between different mixes, and phase relationships of these waves, resulting in
different sounds. You can also use white noise, or switch the sub oscillator OFF. You can
feed a Side Chain signal (from any track) into the synth’s filter (select EXT). You can
select the Side Chain source track from the Side Chain menu at the top of the plug-in
window.
Mix
This slider defines the mix relationship between the main and sub oscillator signals.
When the sub oscillator wave is switched to OFF, its output is completely removed from
the mix.
∏ Tip: High resonance values allow the filter to self-oscillate, which can be useful if you
want to use the filter like an oscillator.
