Grooveshifter
The Grooveshifter plug-in allows you to rhythmically vary recordings, imparting a
“swing” feel to the track. Imagine a guitar solo played in straight eighth or sixteenth
notes. The Grooveshifter can make this straightforward solo swing.
Note: Grooveshifter is reliant on “perfect” matching of the Logic song tempo with the
tempo of the treated recording. Any tempo variations will deliver less precise results.
The reference tempo is the song tempo. The Grooveshifter will automatically follow all
song tempo changes.
The parameters of the Grooveshifter
The Tonal and Beat buttons switch between two algorithms, each optimized for
different audio material that the Grooveshifter plug-in can process. Beat uses an
algorithm optimized for percussive input material. Tonal uses an algorithm optimized
for tonal input material. As this algorithm is based on granular synthesis, it offers an
additional Grain slider, which allows you to set the size of the grains—and therefore
the precision of the analysis.
The Swing parameter determines the amount that even beats will be delayed. A value
of 50% means “no swing,” which is typical for most pop and rock music styles. The
higher the values, the stronger the swing effect.
The Grid parameter determines the beat division reference used by the algorithm to
analyze the audio material. Choose 1/8th if the audio material contains primarily eighth
notes and 1/16 if it contains mostly sixteenth notes.
The Accent parameter raises or lowers the level of the even beats, accentuating them.
Such accents are typical of a variety of rhythmic styles, such as swing or reggae.
Experiment a little to find the right setting for your song.
