8.1 effects overview
The Lifeforms Percussion Sequencer includes 6 unique pattern e ff ects to
expand the musical possibilities of traditional grid style beat programming. Each
channel can run a unique instance of 1 pattern e
ff ect at a time. A master pattern
e ff ect channel is also available that a ff ects all 4 channels of the sequencer. The
combination of the channel e ff ect and the master e ff ect allows for up to 2
e ff ects at a time on each channel. Each e ff ect has 1 parameter that can be
adjusted to dial in the perfect response.
Shift E ff ect
Delays the trigger output of a channel by small divisions of the tempo. Use this
e
ff ect to create half-step or stutter-step drum triggers. E ff ect knob controls the
amount of channel shift. The range of shift is 1/8th to 7/8ths of a beat.
Glitch E ff ect
Probability based glitch e ff ect that creates chaotic gates based on a cascading
chance algorithm. The resulting patterns are always in sync with some division
of the clock, allowing for stuttering but not disjointed patterns. The probability is
set using the e
ff ect knob. The range of the glitch e ff ect is minimal to absolute
chaos.
Density E ff ect
Sets the number and timing of triggers created for each active step. The result
can be anything from a doubling of the trigger to a rolling e
ff ect. The e ff ect knob
controls the trigger density.
Morph E ff ect
Create evolving patterns. The morph e ff ect is a probability based algorithm that
modifies an existing pattern by adding or removing active steps. The e ff ect knob
sets the probability that the pattern will morph.
Swing E ff ect
A classic drum machine e ff ect meant to mimic the feel of a real drummer by
shifting the timing of every other step. The e ff ect knob controls the amount of
swing.
Add/Drop E ff ect
Temporarily add or drop steps from a pattern. The results are similar to the
morph e
ff ect but changes to the pattern are not compounded as the pattern
plays allowing the resulting pattern to stay anchored to the original sequence.
The e
ff ect knob sets the probability that a step will be modified.
