DR. OCTO REX LOOP PLAYER164
• 24 dB Lowpass (LP 24)
Lowpass filters lets low frequencies pass and cuts out the high frequencies. This filter type has a fairly steep roll-
off curve (24dB/Octave). Many classic synthesizers (Minimoog/Prophet 5 etc.) used this filter type.
Filter Frequency
The Filter Frequency parameter (often referred to as “cutoff”) determines which area of the frequency spectrum the
filter will operate in. For a lowpass filter, the frequency parameter could be described as governing the “opening” and
“closing” of the filter. If the Filter Freq is set to zero, none or only the very lowest frequencies are heard, if set to max-
imum, all frequencies in the waveform are heard. Gradually changing the Filter Frequency produces the classic syn-
thesizer filter “sweep” sound.
! Note that the Filter Frequency parameter is usually controlled by the Filter Envelope (see “Filter Envelope”) as
well. Changing the Filter Frequency with the Freq slider may therefore not produce the expected result.
Resonance
The filter resonance parameter affects the character of the filter sound. For lowpass filters, raising the resonance will
emphasize the frequencies around the set filter frequency. This produces a generally thinner sound, but with a
sharper, more pronounced filter frequency “sweep”. The higher the resonance value, the more resonant the sound be-
comes until it produces a whistling or ringing sound. If you set a high value for the resonance parameter and then vary
the filter frequency, this will produce a very distinct sweep, with the ringing sound being very evident at certain fre-
quencies.
• For the highpass filter, the resonance parameter operates just like for the lowpass filters.
• When you use the Bandpass or Notch filter, the resonance setting adjusts the width of the band.
When you raise the resonance, the band where frequencies are let through (Bandpass), or cut (Notch) will become
narrower. Generally, the Notch filter produces more musical results using low resonance settings.
Envelope section
Envelope generators are used to control several important sound parameters in analog synthesizers, such as pitch,
volume, filter frequency etc. In a conventional synthesizer, envelopes govern how these parameters should respond
over time - from the moment a note is struck to the moment it is released. In the Dr. Octo Rex device however, the en-
velopes are triggered each time a slice is played back.
There are two envelope generators in the Dr. Octo Rex, one for volume, and one for the filter frequency (and/or
pitch). Both have the standard four parameters; Attack, Decay, Sustain and Release
! Please refer to “Envelopes - General” in the Subtractor chapter for a description of the basic envelope param-
eters.
