moves the frequencies in the same direction. As you pull the white dot downwards, the filters move together
and allow only a narrow band of frequencies to pass through. You can then move the dot left and right to hear
that band move up and down in frequency.
Moving the white dot horizontally changes the filter
frequencies in the same direction, moving the frequency
pass-band higher and lower
Moving the white dot vertically moves the filter frequencies
together and apart, making the frequency pass-band
narrower and wider
The behavior of the filters is easier to hear than to describe in words. If you play with the filter controls a little
while running a signal with broad frequency content (like a bright synth pad or a drum loop with cymbals)
through Discord, you’ll hear their effect. It may be helpful to set the MIX slider to the far right so that you
hear only the processed signal.
4. LFO Controls
Discord has two low-frequency oscillators (LFOs) that can be used to change, or modulate, the amount of
pitch shifting, the delay times, and the frequencies of the filters. Hence the LFOs can be used to create vibrato
or trill effects by changing the pitch, doubling and chorusing effects by changing the delay time, and tonal
changes by changing the filter frequencies.
The numeric LFO controls determine how fast the output of the LFO varies over time. They
operate either in units of frequency (Hertz, or cycles per second), or in metrical units. The
LFO’s rate can be set from one cycle every 100 seconds (or 0.01 cycles per second,
abbreviated 0.01 Hz) to 14 cycles every second (14 Hz). Click on the unit indicators in the
upper-right corner of the controls (i.e. the words “Hz” and “sync”) to switch between the
two modes.
The WAVESHAPE slider and WAVEFORM buttons work together to control how the LFO’s output varies over
time. The WAVEFORM buttons let you choose one of four waveforms, with sawtooth, pulse, sinusoidal, and
