DR. OCTO REX LOOP PLAYER165
The Amp Envelope governs how the volume of each slice should change over time, from the time it is triggered (the
slice note starts) until the slice note ends. This can be used to make a loop more distinct (by having a snappy attack
and a short decay time) or more spaced-out (by raising the attack time).
Filter Envelope
The Filter Envelope can be used to control two parameters for all REX loops in the 8 Loop Slots; filter frequency and
overall loop pitch. By setting up a filter envelope you control how the filter frequency and/or the pitch should change
over time for each slice.
The Amount parameter determines to what degree the filter frequency will be affected by the Filter Envelope. The
higher the Amount setting, the more pronounced the effect of the envelope on the filter.
q Try lowering the Frequency slider and raising Resonance and Envelope Amount to get the most effect of the
filter envelope!
LFO section
LFO stands for Low Frequency Oscillator. LFOs are oscillators in the sense that they generate a waveform and a fre-
quency. However, there are two significant differences compared to normal sound generating oscillators:
• LFOs only generate waveforms with low frequencies.
• The output of the two LFOs are never actually heard. Instead they are used for modulating various parameters.
The most typical application of an LFO is to modulate the pitch of a (sound generating) oscillator or sample, to pro-
duce vibrato. In the Dr. Octo Rex device, you can also use the LFO to modulate the filter frequency or panning.
Waveform
LFO 1 allows you to select different waveforms for modulating parameters. These are, from top to bottom:

Description
Triangle This is a smooth waveform, suitable for normal vibrato.
Inverted
Sawtooth
This produces a “ramp up” cycle. If set to control pitch (frequency), the pitch would sweep up to a set point (governed by
the Amount setting), after which the cycle immediately starts over.
